The Books of Magic #45 DC Comics (1994)

Part 1 of the 6-part "Slave of Heavens." Tim has released his power into the world with hopes of making it a better place for everyone to live -- but when he learns that the magic he's given up has been stolen by the same changeling who has stolen his face, his past, and his family, he returns to London to confront the thief. Unfortunately, that thief is now quite possibly the most powerful magician of the age, and he would like nothing better than to see Tim dead.
