As a young woman, Laurel misinterpreted a psychic vision, causing the death of her first and only love. She has lived with guilt ever since. Two decades later, struggling to free herself from a toxic marriage, she's pulled to an alternate reality where her beloved still lives. There, she's the dead one, and he and their children are grieving for her. When she tries to contact them, they think she's a ghost.
She desperately wants to remain in her family's reality and connect with them. By enjoying a long, happy life with the man she loves, she can rectify her mistake and free herself from her guilt. But she's running out of time. Every shift between realities damages her body further. And her soon-to-be-ex will stop at nothing to shackle her to a life she despises.
