To Kill a Unicorn (Chronicles of Cain, #1)

The gods are dead. The fae rule Gaia.

Cain used to kill for the fae. The only human to become a member of the Oblivion Guard, he killed one time too many and had enough. Leaving it all behind wasn't as easy as turning in a resignation. But the fae had trained him well and soon it was they who bargained for him to leave Feary and live in exile in Gaia.

Now a tracker for an assassination and bounty hunting agency, Cain doesn't kill anymore. When his mission to track a teenage girl goes horribly wrong, he and the girl end up on the run from powerful forces the likes of which he's never seen before.

That's because the fae have been hiding a terrible secret. The gods aren't dead. In fact, they're very much alive and killing humans they deem too powerful to survive. The girl is in their crosshairs and now he is too.

To make matters worse, Cain discovers he's dying from the curse of Cthulhu. The cure? Eating a living, beating unicorn heart. Cain thought unicorns were extinct, but a mystery party offers him salvation: a unicorn for the assassination of the leader of the Mages Guild.

With the gods, the fae, and the rest of the supernatural world hunting the hunter, the odds don't look good. But Cain has survived too much to give up now. And the high and mighty are about to find out what real fear feels like.
