Rosie Revere is no stranger to flops and fails, kerfuffles and catastrophes. After all, she's an engineer, and engineering is all about perseverance! But, sometimes, Rosie has a really important project to tackle-one that feels much bigger than her. This is one of those times. Rosie's beloved Aunt Rose and her pals make up the Raucous Riveters-a gaggle of fun-loving gals who built airplanes together during World War II. When one of their own, June, is injured and can't paint in the town's annual mural competition, it's up to Rosie to design a painting contraption to assist. All of the riveters are counting on her. After a flop... and another flop... and another flop... Rosie starts to lose hope. But, thanks to some help from her classmates Iggy Peck and Ada Twist (and one neighbor who may not be as mysterious as she seems...), Rosie creates the Paintapoolza! June gets to paint a mural and, together, the riveters and their new young friends rediscover the meaning of Home.
