Years after her best friend mysteriously disappeared from a remote New England island, a young woman returns in search of answers. Orla O’Connor hasn’t been to the isolated New England enclave of Hadley Island since she graduated from high school a decade ago. As a teenager, her best friend Alice disappeared from its shores without a trace—but with plenty of rumors. Now Orla returns to her family’s beachfront home to clean it out before her parents sell it. The island and her best friend’s empty house next door are stirring up memories she would like to avoid. Then there are the locals, always gossiping and watching Orla’s every move. Worst of all, David, Orla’s childhood crush and son of a wealthy Manhattan family, is back for the summer with his new, impossibly pretty girlfriend, Faith.
