Coral is just a normal foster child, trying to get through her last year of middle school as painlessly as possible. However, her whole life changes when she bumps into a boy with a strange name who claims to be her brother. This boy reveals an entirely new world to Coral and shows her where she is meant to be: Atlantis, the element city of water and a place of magic. Coral becomes surrounded by dangers that a thirteen-year-old should only read about, and with a newly discovered family that she is determined to protect, she must find a way to save her new home.
