A true story from Raina Telgemeier, the #1 New York Times bestselling, multiple 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.
