A boy who’s the last in his class to go through puberty tries to fake it till he makes it through a series of cringe-worthy and hilarious events in this balls-and-all coming-of-age novel that’s Judy Blume for boys!

Jack Sprigley isn’t just a late-bloomer. He’s a no-bloomer. He’s in the ninth grade, and puberty is still a total no-show. Worse yet, he hasn’t heard from his friends all winter vacation. He assumes they’ve finally dumped him and his child-like body–except then he finds out that it’s much worse than that. His friends are now so far ahead of him that they’ve started dating and getting girlfriends.

Jack is out of luck. But then he comes up with a plan to catch up and win his friends back. And his plan is perfect: he just has to fake puberty.
