Peter Straub masterfully weaves horror and suspense into a love story unlike any other: the ballad of Ballard and Sandrine. Ballard and his considerably younger lover Sandrine have been brought together by a shared erotic obsession of the darkest kind. As they travel down a remote part of the Amazon River on a luxurious yacht, they spend their days indulging in their macabre pastime. Through a haze of pain and pleasure, the lovers are witness to a series of increasingly sinister portents, dreams and visions that haunt their claustrophobic and disturbing world.
