Ocean of Secrets by Aimee Friedman (author) (UK edition)

The truth lies beneath the surface…

Sixteen-year-old Miranda Merchant is great at science… but not so great with boys. After a major drama with her boyfriend and ex-best friend, she’s secretly relieved to spend the summer on tiny Selkie Island, helping her mother sort out her late grandmother’s estate. But when she steps off the ferry from New York City, she discovers an island rife with legend and lore, steeped in a past her logical mind can’t make sense of. She doesn’t expect to feel such a connection to this mystical place, so filled with languorous charm and strange history. And when she meets Leo, a mysterious local boy, he challenges everything she thought she knew about boys, friendship, reality… and love.
