A true story from Raina Telgemeier, the #1 New York Times bestselling, multiple Eisner Award-winning author of Smile, Sisters, Drama, and Ghosts. Raina wakes up one night with a terrible upset stomach. Her mom has one, too, so it's 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 soon 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.
