Hellhounds Ate My Homework. Justin won Elyssa's heart and saved his dad from rogue vampires, but just when he thinks he can ride off into the sunset on a white horse, trouble not only knocks on his door, it plows through it with hellhounds. Spawn relatives with their own agendas, vampires running amok, and his father marked for death, it seems there's no end to the kinds of monsters out to make Justin's life miserable. It's almost enough to make him long for the days of man boobs, Kings and Castles, and nerd status. With a list of impossible quests growing faster than he can keep up, tracking down the deadliest assassin in the world may prove easier than winning the approval of Elyssa's parents. The clock ticking, and dark forces on his heels, Justin gets a crash course in the mysteries and dangers of the Overworld. But with Elyssa by his side and his growing menagerie of friends, impossible odds suddenly seem possible again.
