Best-selling author Elizabeth Doyle Carey continues the wholesome series that features four 12-year-old girls enjoying life on their Grandma Gee's Gull Island estate. When the other cousins tease Kate for her old-lady pastimes of cooking, decorating, and knitting, she decides it's time to become "cool." Kate draws up a list of things to do. But after Grandma Gee discusses the folly of being cool and the need to focus on what really matters, Kate's not so sure. And then something unexpected happens.
