Based on the lively conceit that it's written by nine older girls at a fictional summer camp who share their collective been-there, done-that experiences, Bunk 9's Guide to Growing Up is a puberty book with a twist, an entertaining, up-to-date, supportive guide that covers the head-to-toe changes that young girls go through as they grow up. Since it is written in the voices of different girls, reading it is like listening to your best friend or older sister giving no-nonsense information, advice, and tips on menstruation, breasts, hygiene, health and nutrition, boys, and all the complicated feelings that go along with these changes. Filled with callouts, doodles, and margin notes, it's a book that's gentle enough for a third grader and thorough enough for a middle schooler, and it's vetted by a pediatrician.
