It is here, in the midst of ancient tensions and new calamity, that two sisters are caught in adeadly web of deceits.Arilou is proclaimed a beautiful prophetess—one of the island's precious oracles: a Lost. Hathin, her junior, is her nearly invisible attendant. But neither Arilou nor Hathin is exactly what she seems, and they live a lie that is carefully constructed and jealously guarded.When the sisters are unknowingly drawn into a sinister, island-wide conspiracy, quiet, unobtrusive Hathin must journey beyond all she has ever known of her world—and of herself—in a desperate attempt to save them both. As the stakes mount and falsehoods unravel, she discovers that the only thing more dangerous than the secret she hides is the truth she must uncover. - from Amzon
