Sourcethief — J.S. Morin

Two worlds aren't big enough for the both of them.

Kryus has found himself a rival of the most dangerous creature he's ever met. The problem? The demon warlock who might kill him may also be the best hope for the future of the empire. With conspiracies swirling around him and an ancient mystery that might hold the key to his survival, Kyrus must navigate the treacherous waters of war and treason before he's swept away by them.

Sourcethief is the third book of Twinborn Chronicles: Awakening. For fans of epic fantasy two aren't looking to start another unfinished series, the Twinborn Chronicles provides multiple new worlds to explore and all the closure you've long been denied.
