On the morning of her wedding, Lena Cross receives an obituary announcing her murder exactly one year in the future. The man accused of killing her is not Julian, the powerful fiancé waiting at the altar, but Aras Vale—a dangerous stranger who claims that Lena has already died forty-seven times and that, in another life, she was his wife. Aras remembers every version of her. Lena remembers none of them. Drawn into the mysteries of Halcyon House, Lena discovers a fractured timeline built from forbidden experiments, erased memories, and two brothers who have spent more than a century fighting over the same impossible past. Every touch awakens another life. Every memory changes the truth. And every attempt to save the person she loves tightens the cycle around them. To survive, Lena must uncover why she once begged Aras to kill her—and decide whether true love means holding on across every lifetime or finally allowing the dead to remain dead. But when the cycle closes, Lena realizes that death was never the end. It was only the beginning.
