Ben Yokoyama is not moving to California. But his parents seem to think otherwise. It's a great opportunity, they say, never mind that Ben will have to leave his best friend Janet behind-possibly forever.

A day into the dreaded cross-country drive, Ben discovers that Janet has secretly stowed away. This is amazing news! Now they can stay friends and start a new life in California. Schemes are hatched, rules are bent, puppies are adopted and bowling alley parking lots set the stage for a brand new pop duo to get their big break.

From the husband-and-wife, author-and-illustrator duo that brought you Ben Yokoyama and the Cookie of Doom comes a series finale so epic it will make you want to read the whole thing over again.
