Pi in the SkyPaperback, 15 April 2014

Joss is the seventh son of the Supreme Overlord of the Universe. His older brothers help his dad rule the cosmos, but all Joss gets to do is deliver pies. That's right: pies. Of course, these pies actually hold the secrets of the universe between their buttery crusts, but they're still pies.
Joss is happy to let his older brothers shine. He has plenty to keep his hands full: attempting to improve his bowling score; listening to his best friend, Kal, try (and fail) to play the drums; and exploring his ever-changing home, The Realms. But when Earth suddenly disappears, Joss is tasked with the seemingly impossible job of bringing it back. With the help of Annika, an outspoken girl from Earth, he embarks on the adventure of a lifetime...and learns that the universe is an even stranger place than he'd imagined.
From the New York Times bestselling author of The Candymakers comes a world-hopping tale that leads the reader deep into the heart of the mysteries of time and space. Plus, there's pie.
