Break the treaty, be destroyed.
We forgot.
Now we pay the price.

Jason Sietinen lives in the shadow of greatness. He’s worked hard to become a TSS officer in his own right, but having war heroes for parents is hard to top.

With the future of the Empire hanging in the balance, Jason must find a way to unite the Taran worlds, including the lost colony of Earth, against the mounting threat. There’s just one problem: how do you fight an enemy you can’t see or touch?

Perfect for fans of epic sci-fi featuring sprawling galactic empires, drama, intrigue, and psionic abilities, Empire Reborn is the first book in the Taran Empire Saga, a new entry point to the bestselling Cadicle Universe. Grab your copy today!

Ancient secrets may be the way forward…

Tarans have reached a tentative peace with the Erebus. While politicians on Tararia address the political ramifications of the new alliance, Jason and the rest of the TSS refocus their efforts on defense.

The Erebus are after something. It’s unclear what, but Jason is convinced they can’t be trusted. The Aesir’s data archive may hold the key to an effective defense, except keeping anything from the Erebus and their seemingly omnipotent abilities will put the fragile Taran Empire in even greater danger.

Fearing for the Empire’s security, the TSS implements a covert plan to upgrade the fortifications across the Taran worlds using ancient technology that has long been buried. Only, those secrets were locked away for a reason, and reopening the archives will initiate a conflict no one is prepared to fight.

Some secrets are worth protecting...

The fearsome Bakzen lurk within a hidden spatial rift, but all-out war is on the horizon. Wil Sietinen is tasked with training a group of twenty young recruits to serve as his officers in the coming battles—collectively, the Primus Elites. He has five years to raise them to full Agents in the Tararian Selective Service, and he'll need every minute.

Training alongside them, and with his partner Saera at his side, Wil still needs to master simultaneous observation, a unique form of astral projection which will be critical to fulfilling his role in the war. But, the closer he gets to achieving the feat, the more likely the mysterious Aesir will come to test him—to see if he's worthy of the Cadicle title.

If he can survive their test, he'll finally uncover the truth the ruling Priesthood has gone to such great lengths to hide.

This character-driven novel with action, romance, and intrigue reveals the true nature of the war as Wil learns the secrets behind the Bakzen's origins.
