A tropical island full of secrets. Two Victorian ghosts, trapped for eternity. And a seventeen-year-old girl determined not to be next. Eulalie Island should be a paradise, but to Addie Spencer, it's more like a prison. Forced to tag along to the remote island on her mother's honeymoon, Addie isn't thrilled about being trapped there for two weeks. The island is stunning, with its secluded beaches and forests full of white flowers. But there's something eerie and unsettling about the place. After Addie meets an enigmatic boy on the beach, all the flowers start turning pink. The island loves you, he tells her. But she can't stop sleepwalking at night, the birds keep calling her name, and there's a strange little girl in the woods who wants to play hide-and-seek. When Addie learns about two sisters who died on the island centuries ago, she wonders if there's more to this place, things only she can see. Beneath its gorgeous surface, Eulalie Island is hiding dark, tangled secrets. And if Addie doesn't unravel them soon, the island might never let her go.
