Michael Ahearn, a professor at a rural college, sheds his comfortable assumptions when he becomes obsessed with a new faculty member from the Caribbean, Lara Purcell. An expert in Third World politics, Lara is seductive, dangerous - and in thrall, she claims, to a voodoo spirit who has possession of her soul. Impassioned and determined, Michael pursues Lara in her native island of St. Trinity, heedless of the political upheaval there. Together they desperately attempt to reclaim all that Lara has lost. Yet island intrigue ensnares them. Lara sacrifices herself to ritual and superstition. Michael is caught unawares in a high-stakes smuggling scheme. In his feverish state of mind, the world becomes an ever-shifting phantasmagoria. He is, himself, possessed.
