This laugh-out-loud illustrated series is "mind-expanding and hilarious!" says Jeff Kinney, author of the international bestselling series Diary of a Wimpy Kid.

"An absolute gem!" Lincoln Peirce, bestselling creator of Big Nate, agrees. "Will get the entire family laughing and learning together," adds Kazu Kibuishi, creator of the New York Times bestselling Amulet graphic novel series.

From the bestselling writer and creator of PHD Comics, Jorge Cham, Oliver's Great Big Universe is a diary-style series following an 11-year-old who's taking on the whole universe-if he can survive middle school first.

Oliver has a lot going on as he starts his first year of middle school-new friends, new classes, new everything. But at least there's one thing that still makes sense: science!

Determined to be an astrophysicist one day, Oliver explains everything he learns-like how the sun burps, how ghost particles fly through you, the uncanny similarities between Mercury and cafeteria meatballs, and most important, how the Big Bang is basically just like a fart in the school hallway.

Also, there are time-bending black holes, exploding supernova stars, and aliens! Well, there could be aliens.

Oliver finally feels like he's starting to figure things out . . . but can he stay out of the principal's office or catch a break from his annoying sister?
