Written by Jeffrey Brown

It’s hard to believe this is Roan’s last year at Jedi Academy. He’s been busier than ever learning to fly (and wash) starships, swimming in the Lake Country on Naboo, studying for the Jedi obstacle course exam, and tracking down dozens of vorpak clones–don’t ask. But now, someone is setting him up to get in trouble with everyone at school, including Yoda. If he doesn’t find out who it is, and fast, he may get kicked out of school! Why can’t middle school just be easy. . . <p/>This incredible, original story captures all of the humor, awkwardness, fun, and frustrations of middle school–all told through one boy’s comics, journal entries, letters, sketches, e-mails, and more.

And Grandpa’s woolly long johns make a super-whizzy slide! The text is in verse, the illustrations are big and bright, and kids who open this book will giggle from first page to last.

  • Gordon: Bark to the Future! - It’s all up to Gordon now. His partner has been captured. His superior officer has been neutralized. And his distress calls to P.U.R.S.T. (Pets of the Universe Ready for Space Travel) have gone unanswered. That means he must fight the aliens alone! But Gordon’s not a fighter — his deadliest weapon is his mind. So what’s a genius dog to do? Time travel, of course! He’ll use his new time machine to travel back in time, then he can stop the invasion before it happens. But there’s a malfunction: instead of sending him back five days, the time machine sends him back five years! And now he’s out of fuel! With only his wits to depend on, can Gordon get back to the future in time to save his friends and his humans? This laugh-out-loud junior graphic novel is part of Ashley Spires’s hugely popular P.U.R.S.T. Adventure series. Gordon the dog is a favorite character from Spires’s companion series about Binky the cat. Not too text-heavy, these titles are perfect for emerging readers, though the nonstop action, melodrama and physical comedy make them popular with all children (and adults, too!). With lots of details to look for in the artwork — such as hilarious sound effects and animal facial expressions — these titles are terrific for developing visual literacy in beginning readers. This story showcases the character education attributes of responsibility, courage and perseverance.

  • Rocket and Groot: Stranded on Planet Strip Mall! - After battling deadly space piranhas in Sector 7 of the Cosmos, Rocket and Groot crash-land on a planet made entirely of strip malls!

Featuring full-color illustrations throughout, a spectacular gatefold, plus how-to-draw pages in the back, it’s an outer space adventure that demonstrates a giant leap for bookmaking and a giant leap for any kid looking for their next go-to series. AstroWolf, LaserShark, SmartHawk, and StinkBug are animals that have been hybridized to find other planets for humans to live on once we’ve ruined Earth. So off they rocket to the Plant Planet! Will that planet support human life? Or do Plant Planet’s inhabitants have a more sinister plan? AstroNuts Mission One is a can’t-put-it-down page-turner for reluctant readers and fans ready to blast past Wimpy Kid.
