"A laugh-out-loud tour de force." --Kirkus, starred review

Ever wish you had a way to magically solve all of your problems? The kids at Hopewell Elementary School might have exactly what you're searching for--just walk down the hall and stop at Locker 37.

Carson Cooper realizes that he has a very inconveniently located stain on his pants. That is NOT the way to start things off on the first day of school. Fortunately, Carson finds a letter written by last year's fourth graders stuck to the bottom of his desk with some watermelon bubble gum. The note explains the existence of Locker 37, which will provide a solution to any problem! And when Carson sneaks off to the locker it does, indeed, provide a solution--an eraser! But the problem is that the eraser works a little too well, erasing anything it's rubbed against three times. ANYTHING.
