At the edge of a blood-stained, ancient spring, a pagan goddess awakens from a long sleep thirsty for sacrifice… 

When down-on-his-luck busker, Evan, arrives at the Christmas market, he expects to play tunes of festive cheer for the merry crowd — and to reap the reward for his music. 

But when an icy winter storm blows in and disaster strikes, Evan must make a choice that can only end in… A Midwinter Sacrifice.

A dark Christmas short story set in the bleak midwinter by USA Today bestselling author, J.F. Penn. 

Someone out there is murdering the living… and desecrating the dead.

Detective Jamie Brooke is a woman in the depths of despair. Her career is on the ropes. Her daughter is dying — there are only hours left before the end, and decisions have to be made.

Museum curator Blake Daniel is a man on the edge of destruction. Cursed with the ability to “read” objects — to see where they’ve come from, and the bloody histories they experience — Blake splits his time between working as a researcher at the British Museum… and binge-drinking to forget his nightmare visions.

Together, these two broken souls are all that stand between London and a serial killer. A young woman has been murdered, her uterus and unborn child removed during a gala event at a college of surgeons, any of whom could have committed the crime. The only clue is a small ivory figure of a woman undergoing a Cesarean section, dating to the seventeenth century.

Body modification, grave robbery, Nazi eugenics, a laboratory that specializes in extreme genetic experiments. All come together to create a mystery unlike any Jamie has experienced, and a danger greater than any Blake has ever seen in his visions.

It will take all Jamie’s detective skills, and all Blake’s psychic abilities, to find the killer. To end the murders. To stop something that wants to destroy all that is good… and leave behind only DESECRATION.

Desecration is the first book in a thrilling new series by New York Times and USA Today bestselling author J.F. Penn: a blend of crime, psychological thriller — and the supernatural. Click “buy now” and find out what’s behind the world you think you know…

When fire falls from the heavens… will the whole world burn?

Dr. Morgan Sierra, an Oxford University psychologist with a deadly past, doesn’t know the answer to that question — and doesn’t care. All she knows is that her sister and niece have been abducted, held hostage for the stone pendants that Morgan and her sister wear: two of twelve relics once owned by the original Apostles.

Forged in fire and wind, drowned in the blood of martyrs, the twelve Pentecost stones have been kept secret for two thousand years. But now the Keepers of the stones are being murdered, and the relics stolen by Thanatos, a shadowy group dedicated to remaking the world into a living Hell.

The authorities are clueless; the world lies helpless. And Thanatos grows more powerful with each stone they take.

Enter Jake Timber — agent of ARKANE, the British agency tasked with investigating the supernatural. Jake knows some of the secrets Morgan needs to save her family, but can’t stop Thanatos without her help. Only together can they stop Thanatos before the stones are captured, before Morgan’s family is murdered, and before the world is changed forever.

From flooded ruins in Italy, to religious sites in Israel, to the far reaches of Iran and Tunisia, Morgan and Jake must race across the world to find the stones before Thanatos gathers the relics and uses their power to turn Earth into a living Hell.

But every step they take brings Morgan and Jake closer to the end. To the knife edge between salvation and madness. To the moment when Morgan will have to decide whether she will save her family… or save the world.

Time is running out. Thanatos draws near. And the day of Pentecost is at hand.

Two billion people are about to die… and they’re the lucky ones.

When a man in a hospital gown jumps to his death from the Western Wall in Israel, the authorities think it’s just another victim of Jerusalem Syndrome: a religious psychosis triggered by a visit to the holy city.

But when a second victim ritually disembowels himself, it’s the sign of much worse to come. Thanatos — a fanatical group dedicated to the destruction of the world — is on the move again.

The only ones who can stop them are ex-Israeli military psychologist, Oxford professor, and religious expert Morgan Sierra; and Jake Timber, agent of ARKANE, the British agency tasked with investigating — and sometimes saving the world from — the supernatural.

Last time, Morgan and Jake worked together to stop Thanatos from bringing about a dark version of Pentecost. This time, Thanatos is mixing science with sacrilege — combining the Devil’s Bible with mind-control technology to murder a quarter of the human race.

Together, Morgan and Jake will travel from the hallowed halls of Oxford, to the labs of a biotech company with a dark agenda, to a chapel made of human bones. They’ll go anywhere, do anything, to stop Thanatos.

But they have to hurry.

Thanatos is on the rise. Apocalypse is at the gates. And the only way to save a quarter of the world is for Morgan to uncover the secrets of her past… at the cost of her own future. Death awaits in a Crypt of Bone.

Escape into three more ARKANE adventures…

Valley of Dry Bones

The power to raise the dead… will mean the end of all life.

Jake Timber, agent of ARKANE — the secret organization charged with protecting the world from supernatural threat — is flying solo. 

His usual partner, Morgan Sierra, is on leave, still reeling from a recent brush with death. But evil takes no vacations, so when the corpse of a monk is discovered beneath a New Orleans cemetery — cruelly murdered, his body broken and his flesh carved with occult Voodoo markings — Jake knows it’s bad news.

But even he’s not ready for the truth: someone is looking for the Hand of Ezekiel.

Imbued with the power to raise the dead, the Hand was broken into five pieces, but now someone has found it… or something like it, because someone is killing people in New Orleans, then raising them from the dead as monsters.

In over his head, Jake needs Morgan’s help if he hopes to beat back this evil. But even if she comes back to help, will it be enough? The Hand of Ezekiel is being assembled. The dead are rising from the grave. 

And the power to stop it all can only be found in the land of the dead… in the Valley of Dry Bones.

Tree of Life

They will create Paradise on Earth… by killing everyone in the world.

When a fragment of an ancient manuscript is stolen, it’s more than simple theft — it’s the beginning of a race to discover the original Paradise: the Garden of Eden itself. The manuscript contains part of a map to the fabled garden, and to the Seed at its heart: a Seed that can rekindle life from death.

But Morgan Sierra and Jake Timber know it’s never that simple. Agents of ARKANE, the secret British agency tasked with uncovering — and at times burying — the secrets of the supernatural, Morgan and Jake begin their search for the Seed at the heart of Eden. 

But they’re not alone. An eco-warrior group also wants the seed, hoping to use it to return the Earth to “perfection” — even if that means killing everyone alive to do it… starting with Morgan and Jake.

On the run, outnumbered and outgunned, Morgan and Jake will have to use every asset at their disposal, every skill they know. From Portugal to Brazil, Amsterdam to the Caribbean — the agents of ARKANE will travel the globe in search of the thing that can save us all, or end us in an instant: the Seed at the heart of the Tree of Life.

Tomb of Relics

A supernatural relic. A thousand-year-old conspiracy. A madman who turns death into art. It's all in a day's work for the agents of ARKANE.

When a priceless relic disappears from Canterbury Cathedral, ARKANE – the agency tasked with protecting the world from supernatural adversaries – fears the worst… and sends its best.

Now, ARKANE agents Morgan Sierra and Jake Timber are on the job. Across Europe, through historical cities and into spectral forests forgotten by time, Morgan and Jake will follow the bloody trail of hidden relics wherever it leads, whatever the cost.

But even they aren’t ready for what’s coming.

Their hunt will lead them beyond danger, beyond darkness to the shadowed heart of a hidden citadel where lives an evil unlike any they’ve ever seen… and to a dark choice that will change them both forever.

In a world gone mad, only the insane can rule.

Still reeling from the death of her beloved daughter, Detective Jamie Brooke needs time to grieve and to heal. What she gets is a call to murder and madness: a prominent psychiatrist has been tortured to death, and it’s up to her to uncover the people responsible, and stop them before they can kill again.

Turning to her friend, Blake Daniel — an antiquities expert cursed with the psychic ability to “see” the bloody histories of objects — Jamie begins an investigation that will take her to the most infamous asylum in history, and a place where insanity is born. A place where rules don’t apply, and where madness is the only law.

She has no idea what she’s getting into. Because Jamie doesn’t know the true history of Bedlam Asylum, the depraved experiments that went on there, or how it leads to the string of murders that could bring the country to its knees.

Worst of all, she doesn’t know about Blake’s connection to Bedlam, to the murders, and to the people willing to execute anyone who stands in their way. And Blake himself doesn’t know the full evil of his own past, or that his gift has put him in the sights of a group who want to use him as a guinea pig for their darkest experiments.

The answers are coming. But some answers bring only pain. Some answers bring only death.

And the worst answers of all bring only DELIRIUM.

The second installment in the thrilling Brooke and Daniel series, Delirium (by New York Times and USA Today bestselling author J.F. Penn) presents a chilling world where insanity is the only law, and madness the only way to survive. Get your copy today, and experience Delirium for yourself!

A relic, stolen from the heart of an ancient city. An echo of nationalist violence not seen since the dark days of the Second World War.

** From New York Times and USA Today Bestselling Author J.F.Penn **

Budapest, Hungary. When a priest is murdered at the Basilica of St Stephen and the Holy Right relic is stolen, the ultra-nationalist Eröszak party calls for retribution and anti-Semitic violence erupts in the city.

Dr Morgan Sierra, psychologist and ARKANE agent, finds herself trapped inside the synagogue with Zoltan Fischer, a Hungarian Jewish security advisor. As the terrorism escalates, Morgan and Zoltan must race against time to find the Holy Right and expose the conspiracy, before blood is spilled again on the streets of Budapest.

One Day In Budapest is a chilling view of a possible future as Eastern Europe embraces right-wing nationalism. A conspiracy thriller, where religion and politics intersect.

One Day In Budapest features Dr Morgan Sierra from the ARKANE thrillers, but is a stand-alone novella and can be read separately from the ARKANE series.

In a perfect world, the deviant cannot be permitted to live.

Someone has been murdering sex workers and those on the margins of the city, flaying the skin from their bodies, and leaving them as a warning to others like them.

Jamie Brooke used to be a cop. But there’s no place on the force for someone who wasn’t fast enough to stop a killer from attacking Parliament and killing a friend.

Blake Daniel is on the verge of being fired, his life and his mind in tatters. Cursed with the ability to “see” the murderous past of certain objects and relics, his life has become a waking nightmare — his only relief at the bottom of a bottle.

They’ve had their fill of danger and death, and just want to be left alone… but evil isn’t done with either of them. So when the body of a priest is discovered — stabbed and slashed, skin flayed off, and white feathers stuffed in his mouth — Jamie and Blake find themselves enmeshed in the web of murders terrifying the city.

The community is paralyzed. The police are powerless — or maybe even covering up the murders. It’s up to Jamie and Blake to solve their darkest mystery yet.

And they have to hurry. More death is coming. Because the murderers want one simple thing: perfection. And that can’t exist in a world with any DEVIANCE.

Blending crime and psychological thriller with a touch of the supernatural, Deviance is a one-of-a-kind adventure from the mind of New York Times and USA Today bestselling author J.F. Penn! Get your copy today, and dive into Brooke and Daniel’s toughest case yet!

It is the seat of judgment. The pinnacle of holiness. It is the Ark of the Covenant… and it’s the most dangerous weapon in existence.

A group of fanatics wearing masks of Egypt’s gods slaughter the curator of Cairo’s most famous museum. A cleaner in Washington, DC, discovers a decapitated head on top of a replica of the Ark of the Covenant. And someone is sharing videos of the deaths with extremists all over the world.

It’s a job too big — and too strange — for the normal authorities, but it’s right up the alley of ARKANE, the British agency tasked with investigating mysteries on the edge of the supernatural.

Normally ARKANE would send its best agents: Morgan Sierra, ex-Israeli military and professor of psychology and religion; and Jake Timber, a man as mysterious as he is dangerous.

But Jake is in a coma, nearly killed on a previous mission — so Morgan will have to go it alone. Because the death toll is rising, and there’s no time to wait.

In over her head, in constant danger. Pursued by vicious mercenaries bent on revenge, hunted by assassins willing to do anything for their cause. But Morgan can’t stop, because the Ark of the Covenant is the prize, and it may be more than a simple religious artifact.

It may be the secret to ancient alchemy, and the unlocking of a scientific breakthrough that could save the world… or end it.

A mix of Raiders of the Lost Ark, James Bond, and The Da Vinci Code, Ark of Blood is a mesmerizing adventure by New York Times and USA Today bestselling author J.F. Penn. Grab your copy today, and get lost in the world of ARKANE!
