Cassie Barrett, a renowned anthropologist, and Alex Rivers, one of Hollywood's hottest actors, met on the set of a motion picture in Africa.

A frightening pattern is taking shape—a cycle of hurt, denial, and promises, thinly veiled by glamour. Torn between fear and something that resembles love, Cassie wrestles with questions she never dreamed she would face: How can she leave? Then again, how can she stay?
