The latest book in Davide Cali and Benjamin Chaud's internationally acclaimed I Didn't Do My Homework Because . . . series is out of this world!

It's a race to do homework—in space! But first, there's a spaceship jam. Then there's the moon detour, the Mars alien exploration, and a stop on the gravity-defying International Space Station. And that's just the beginning! Henry and Ali want to get their homework done—they really do! But how are they supposed to study the solar system when they seem to be swept up in an endless series of interstellar surprises? For Ages 6 and up.
