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 WWII. 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. After various flops, Rosie starts to lose hope. But, thanks to some help from two classmates (and one neighbour 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 friends rediscover the meaning of home.
