In book 4 in the Winnie Years series, best friends Winnie, Dinah, and Cinnamon head to a camp in South Carolina to help save the population of sea turtles.  With a houseful of other teens, the boy-crazy trio make new friends and deepen their relationship with each other.  While Dinah and Cinnamon find boyfriends this summer, Winnie feels insecure about her boyfriend, Lars, at home in Atlanta.  While mostly a funny, summer romp of a story, I would caution elementary school that there is talk of erections and bare boobs.  Cleverly, the author has eighth grade Winnie making up a “To Do Before High School” list — subsequent chapters are named after items on this list.  Readers cheer Winnie on as she is able to one-by-one cross off items from the “To Do” list.
