Isabelle Scotts life may not be easy, but she loves it. She is a star swimmer and lifeguard, has great friends, and has been spending the summer with Brayden, a cute surferthough theyre just friends. But her grandmother, with whom shes lived since her mother died five years earlier, is declining quickly, and Izzies whole world is upended. Shes whisked away from the poor, rough neighborhood where she grew up to live with her aunt, uncle, and cousins in the exclusive Emerald Cove. Mirabelle Monroe leads a charmed life: her father is a former baseball star about to run for the United States Senate. Shes popular and beautiful and has a super cute jock boyfriend. But when her cousin, Izzie, comes to live with her family, her well-ordered world starts to unravel. It doesnt help that Miras best friend and queen bee, Savannah, hates Izzie from the start, maybe because Izzie seems to be so close to Savannahs boyfriend, Brayden. And Mira doesnt know whether to choose her friends and status at school or her family. As Izzie and Mira try to navigate their new lives, family secrets are dug up and the girls learn what friends and family truly mean.
