Kurt Busiek's Astro City Vol. II: Confession Book

Brian Kinney has left his rural home, seeking adventure in the big city - Astro City. After literally working his way into the super-hero scene as a busboy and waiter, Brian attracts the attention of Astro City's vigilante Confessor. Dubbed Alter Boy, Brian becomes the Confessors sidekick. While Astro City suffers under the looming threat of a serial killer on the loose and the city government moves to ban super heroes altogether, Brian questions the actions of his mentor. If that weren't enough, there just may be an alien invasion looming!
