Ruby and her three BFFs go camping in this third installment of the relatable and empowering The Invincible Girls Club chapter book series that fans of The Baby-Sitters Club will love! Ruby’s life turns upside-down when her parents give her some big news: she’s going to be a big sister! She is a little worried about the new arrival, so her dad takes her and the rest of the Invincible Girls camping for the weekend, where she plans to become one with nature, bond with her friends and Dad, and get away from technology for the weekend. However, she finds that things are not as easy as they seem. She forgets a key item to bring, her friends don’t seem as excited as she is...and she kind of forgot about the bears who like to visit the camp sites! Ruby wonders if maybe it isn’t about leaving everything behind for an escape into nature but finding the perfect balance.
