Lindsey Trent gives little thought to the nightmares that plagued her childhood until a man she believed dead appears in her dream. He delivers a cryptic warning, telling her she may have no choice but to dreamstride once more, and vanishes. In his wake, a stranger arrives who welcomes her back even as he runs her through. After waking with bruises where the sword pierced her, she seeks answers and finds herself enmeshed in a dream realm every bit as real and dangerous as the waking world, where not only injuries but death is possible. Her fellow dreamstriders view her with hostility and fear. Only one stands with her, and as they explore their relationship in both worlds, he pushes her to remember her abilities, for a dreamstrider who hunts his own kind seeks Lindsey as his latest prey.
