Orphan Jack Templar has no memory of his parents and only the smallest details from his Aunt Sophie about how they died. The day before Jack’s fourteenth birthday, things start to change for him. At first it’s great: A sudden new strength helps him defend his nose-picking friend “T-Rex” from the school bully, and even his crush, Cindy Adams, takes notice. But then a mysterious girl named Eva arrives and tells him two facts that will change his life forever. First, that he’s the descendent of a long line of monster hunters and he’s destined to be in the family business. Second, that there’s a truce between man and monster that children are off-limits…until their fourteenth birthday! Jack has only one day before hundreds of monsters will descend on his little town of Sunnyvale and try to kill him.
