To Tempt a Viking by Michelle Willingham

She belongs to another man. But he’s about to claim her heart…

Ragnar Olafsson has lived with the torment of watching his best friend claim the woman he secretly loves. To bury his desire, he’s become a ruthless warrior, his heart locked behind iron walls.
When Elena is kidnapped, Ragnar risks everything to save her—only to find themselves stranded together, far from rescue. Alone in the wilds, every stolen glance and forbidden touch awakens a hunger neither can deny.

She belongs to another man, and he has sworn an oath to protect her. But temptation burns hotter than loyalty… and some passions cannot be caged.
