In one month Jeremy Fink will turn thirteen. But does he have what it takes to be a teenager? He collects mutant candy, he won't go more than four blocks from home if possible, and he definitely doesn't like surprises. On the other hand, his best friend, Lizzy, isn't afraid of anything, even if that means trouble now and then.

Jeremy's summer takes an unexpected turn when a mysterious box arrives. According to the writing on the box, it holds the meaning of life! Jeremy is supposed to open it on his birthday, but the keys are missing, and only the keys can open the box without destroying what's inside. Jeremy and Lizzy set off to find the keys, but when one of their efforts goes very wrong, Jeremy starts to think he'll never be able to open the box. But what he doesn't know is that there just might be other ways to find out the meaning of life.

Lively characters, surprising twists, and thought-provoking ideas make Wendy Mass's latest novel an unforgettable read.
