Growing up, Cassie Waters spent every waking moment of every summer at her swim club (which was conveniently located at the end of her street). These days, Cassie lives in the suburbs of New Jersey, writing and editing books, hanging out with friends, and having lots of fun. Over the years, Cassie has written dozens of books, but the Pool Girls series is nearest and dearest to her heart. She doesn’t make it to the pool nearly as often as she would like these days, but she is still very good friends with the girls she used to hang out with at her swim club.
