However, the curse can be broken if a daughter of Morrigan falls in love with him. Finding such a woman seems impossible, until he discovers a beautiful stranger beneath his tree where only a few final leaves remain.

That is, until she stumbles upon an enchanted castle in the middle of a blizzard and a man who can not only unlock the secrets to her past, but also her heart. With time running out, is it possible for passion to give way to love? Or are they both doomed to the fate of their curse?
