Query: Mediocre hanger-on

I wish I could say that this book were great. Unfortunately, it is merely a mediocre hanger-on of the Harry Potter genre. Meet Bobby Pendragon, our 14-year-old protagonist: he is often conceited, stuck-up, plagued by an inferiority complex, a whiner, and none too bright. Just before he is to play in his school's basketball game, as their "star player," he finds out that he is a Traveler, who will be swept into a tunnel across time and space to save another planet from destruction. His favorite phrase is "I can't, I can't, I can't!" The writing is uninspired, the action contrived, and the dialogue clumsy.
