Azeril can't remember anything about his life before he came to live as a ward of the Church-except his desire to assassinate wizards. He's become the Church's most cunning weapon. By day, Az hides in plain sight as a student, with only his beloved obsidian knife as a reminder of who he is. Until one night, when a wizard recognizes him from his past. The killer in Az never misses his mark, but he can't destroy the only potential link to his life before this. For the first time, Az has a lead on who he used to be-if only he could escape the watchful eye of the High Priest long enough to investigate. Azeril discovers that the line between good and evil-the primal forces of the Fire and the Chasm-is as shifting as his own moral compass. And the truth about who he is will put his entire world in danger.
