Shadow Mage (Shadows of Magic Book 2)

An immortal man, counting the days before a demon takes over his body and brings ruin to the world.
A young assassin, riddled with social anxiety, sent to kill him, discovering that it's extremely difficult to kill a man who cannot die. An unlikely friendship, with the fate of the world at stake. Magical beasts roaming the land. Cracks in the very foundation of magic itself. A talking-- well, rambling-- pillar of fire infused with the soul of a certain long-winded old wizard. Can Finn save the world again, this time from himself? Can Sarai figure out how to kill him, or at least how to successfully navigate a basic social interaction without crumbling into a ball of neuroses or stabbing someone? Who the heck thought letting Isabelle teach a class of impressionable youngsters was a good idea? The answers to these questions, and more, lie in Shadow Mage, the long-awaited sequel to Sarah McCarthy's Shadows of Magic
