Aristotle Brown and his partner at work and in life, Eoghan Sapphire, love working together in the agency they call home. The I.S.R. (Interspecies Response) branch of the U.S. Marshals Service is an exciting place to work…if you don’t mind running into the occasional toe-sucking vampire, adorable little multi-eyed alien, or mountain cave-dwelling dragons. Then again, some of their most rewarding work has centered around forming bonds with various shifter populations who thrive along the vast highways and byways of California. They spend a lot of time on the road but being together makes it all worthwhile.

For months now, they’ve been trying to assist a vampire fugitive get back home to his clan…and his throne. King John Townsend has been waiting patiently, knowing every day that goes by brings his people more misery under their new, illegitimate king, Tillis Bradshaw. Bradshaw is an evil vampire whose ruthlessness and greed drive all his decision making. This of course includes an ever-expanding network of nationwide drug trafficking as well as the takeover of synthetic blood factories vampires need to survive. Not to mention the fact that he’s starving his own people.

Eoghan and Ari have known for a while now that someone at the Agency is in bed with Bradshaw and worse than that, there’s a mole in the L.A. office. They’ve had to work in secret with the assistance of their boss, Deputy Chief Arizona Priest. When they get home from what promises to be their last venture outside of California to begin planning the ousting of Bradshaw and his evil minions, neither man is prepared for the disappearance of their boss or the reappearance of an evil nemesis.

Join Ari and Eoghan with all their friends and allies in their final adventure as they face off with an evil neither man could’ve imagined.
