All Jasper wanted was to find a book that would make Molly, the frowning dog at the library, stop frowning... But even though he's so, so, so careful, the book he comes home with suffers one accident after another, until Jasper has no choice but to throw it in the trash. Now he has to face the facts: he's a Book Killer. And not only that, he'll have to pay for the dead book or they'll never let him back in the library again. How much? Too much! Way more than he can afford. Jasper's friend Ori jumps in to help, and they come up with a plan. But will it succeed? Or will Jasper be banned from the library forever?
