Liv has to run. Erik has to hunt her. The curse makes them do both. After Liv's Viking village raids Iona Abbey in Scotland in 795 A.D., Liv and Erik are afflicted with a curse of the heart that gives them immortality. With the help of a monk sworn to guide them, they must find ancient relics to break the curse. But this living curse doesn't want to die. It lingers on, and Liv soon discovers that killing Erik over and over to keep him from stopping her from getting the relics isn't the real problem. The matters of the heart make living without each other more painful than dying. Even as their hearts pull them together throughout the ages, Liv fights the constant urge to be with him. If she doesn't destroy the relics, the curse will rend itself upon them all and bring chaos, and they will die with broken hearts anyway.
