Oliver has a lot going on starting 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?
