On a stormy night, Stella narrowly avoids hitting a badly injured black wolf. Believing it is dead, she drags it off the road and leaves. The next morning, a wounded stranger appears at her door and claims he was the wolf. She takes in the amnesiac Grayson, unaware of the powerful identity he has forgotten. As danger closes in, Stella discovers that she is the long-lost heir to the Ross family—and that someone knew the truth before she did.
