The sun will come out

Summary: "Twelve-year-old Bea Gelman and her best friend Frankie are planning the BEST SUMMER EVER at Camp Shalom―a sleep-away camp. But at the last minute, Frankie bows out, leaving painfully shy Bea on her own. Just talking to strangers causes Bea to break out into ugly, blotchy hives. As if the hives weren't bad enough, Bea gets pranked by a couple of mean girls and is betrayed by someone she thought was a new friend. Bea has had enough! She decides to spend her summer in the infirmary far away from everything that’s stressing her out. No more boys (including her crush, Jeremy), no more horrible mean girls, and no more fake friends! At the infirmary, Bea meets Harry, a boy living with a disease that’s way more intense than stress breakouts. Inspired by Harry’s strength and positive outlook, Bea decides to face her fears―in a big way." -- goodreads.com
