Editorial Reviews


The Best Vampire Fiction Releases of 2011: "...the ambitious, grand-scale, science fiction backdrop and labyrinthinely plotted storyline was impressive, to say the least."
--Paul Goat Allen, Explorations: The Barnes and Noble SciFi and Fantasy Blog

"Vampires, shifters, justice fighters, protectors, magic and advanced technology; at first glance, an impossible combination but one that will stir every reader's imagination and leave you asking - What just happened? Yes, the book is that good."
--Valentina Heart, The Romance Reviews

More About the Author

By profession, I am a hematopathologist, a laboratory physician who specializes in diagnosis of diseases of blood, bone marrow, and lymph nodes, such as leukemia and lymphoma.

The Interscission Project is space opera/time travel/gay romance. My previous works are part of an unrelated paranormal romance series, the Pact Arcanum Saga, which consists of five books: Sunset, Cathedral of the Sky, Sunrise, Moonlight, and Starlight. It is best described as non-explicit, near-future gay vampire space opera. Yes, I realize the irony that I am a blood doctor who writes about vampires. ;)

Note: While each series conforms to standard conventions regarding the romance genre overall, I do not guarantee an HEA or HFN ending to any individual book within the series.

Sunset is the first novel in the Pact Arcanum series by Arshad Ahsanuddin. Kind of. There are currently two books in the series, and although Sunrise is the chronological beginning of the story, Sunset is intended to be read first. This allows the author to drop the reader immediately into a thrilling moment in the story, in which a terrorist event results in the inadvertent revelation that a few species of "meta-humans", including vampires, have been living among humans secretly for centuries in parallel societies, complete with their own complex political structures, alliances, and issues. Although the reader is dropped into the story midway, all of the necessary backstory is revealed along the way when needed (sometimes the dialogue used to introduce relevant backstory seems a little contrived, but it does the job).

Overall, I thoroughly enjoyed the book. The writing is clean, artfully composed, and engaging; the author's intelligence and precision shine through in impeccably crafted sentences. The beginning and end are absolutely thrilling - the action is gripping, as is the drama of the individuals facing those intense situations - towards the end, I could not put the book down. The political tensions, both between the humans and meta-humans and across the meta-human society, are palpable and credible, and they help to give the story depth and make it engaging, causing the reader to really think about who is right, or, as in real life, if more than one side is right.

The book is not without its flaws. It is far more story-driven than character-driven, which makes for an engaging story overall, but sacrifices the reader's emotional identification with the characters.

I came for the world-building; I stayed for the characters. This author's got brains and heart.

As other reviewers have said, Sunset begins by plunking readers in the middle of intense action. Through the eyes of a minor character, we watch a terrorist take over a televised awards ceremony in the near future with the intention of blowing up an entire city. The major characters cope with the catastrophe by using technology, skills, and jargon that can be baffling. By the end of the first chapter, we, like the minor character, are thoroughly confused--but we're intensely curious. We eagerly follow the major characters back where they came from to try to figure out who they are and why they do what they do, and we end up witnessing a global war.

Ahsanuddin has created not just a plot-driven novel but an actual culture of vampires and related "meta-humans." I find the culture the true attraction of this work. Ahsanuddin's vampires are complex, conflicted; a tragic mixture of human and immortal, instinct-driven animal. They fall deeply in love, protect their loved ones at immense cost, grieve for centuries over the pain they've inflicted. Their foils are called Sentinels, enhanced mortals engaged with the vampires in an ageless war which can end only when one race or the other is exterminated. But Sunset is not so much about this war as it is about the war between these meta-humans and actual humans. Readers may be surprised to find themselves rooting for the bloodsuckers.

I gave this book a three-star rating because Ahsanuddin is still learning his craft. That is, I want to leave room for more stars in reviews of fufure books. Sunset and Sunrise both resemble enthralling paintings viewed through scratched glass: the art is there, but it's obscured.

This is not the book I normally read, so please take everything I'm about to say with some salt. I think if you like to read vampire novels set in highly charged political settings, then you would probably give this four stars.

Me, not so much. It took awhile to get interested in the characters, and even then, there is a lot of jargon that kept me confused almost all the way through the novel.

Once I did get interested in the characters, the story began to speed up, and by the end, I was definitely enjoying myself.

This author is so lost in a fantasy world that he fails to help the reader to enter that world with him. It is like trying to understand someone else's psychosis when they have limited verbal skills. It's not fascinating -- just frustrating. The book has such a choppy, disjointed narrative that I finally deleted it from my my kindle. I read a lot of close to mediocre fantasy literature but this was too much work even for a somewhat voracious reader. Save your time and money. There are lots of better things to read -- in fact most fantasy literature, no matter how unformulated and implausible, surpasses this book by leaps and bounds. BTW, if you think this sounds like it comes from a literary curmudgeon, trust me when I say I give almost anything 3 to 4 stars.

Sunset is an amazingly detailed look into the society of meta-humans living hidden in North America. I usually don't enjoy vampire books, but this one is an exception. There are three races in the hidden society Nightwalkers, Daywalkers, and Sentinels. Nightwalkers are the typical vampires, Daywalkers are vampires that have been cleansed of their demonic taint and reclaimed their souls, and Sentinels are the soldiers that are genetically designed to kill vampires. Daywalkers are a fairly new race, but Nightwalkers and Sentinels have been at war for thousands and thousands of years. In North America however there has been a truce reached between the three races and they now live in relative harmony.

When a terrorist threatens to nuke L.A. Nick, a Daywalker, reveals himself and exposes the hidden society to the world. Arshad Ahsanuddin has created an intricate political structure involving all three races. The vampire society is divided into houses that all have alliances and enemies as well as Nightwalkers hating Daywalkers and Sentinels killing all vampires regardless (outside of the alliance). The story is action filled and intense. This book is fantastic and I cannot wait to read book two and book three (this summer hopefully).
