Raina wakes up one night with a terrible upset stomach. Her mom has one too so its probably just a bug. Raina eventually returns to school, where she's dealing with the usual highs and lows: friends, not-friends and classmates who think the school year is just one long gross-out session. It soons becomes clear that Raina's tummy trouble isn't going away... and it coincides with her worries about food, school and changing friendships. What's going on?

Raina Telgemeier once again brings us a thoughtful, charming and funny true story about growing up and gathering the courage to face and conquer her fears.
