Storm of Desire - McMaster Bec

The old eddas speak of dreki—fabled creatures that haunt the depths of Iceland’s volcanoes and steal away fair maidens.

Haakon wants none of such myths. For years he's searched for the beast that stole his wife, desperate to slay the golden dreki and rescue his precious Árja. He has sacrificed everything to find her—including his honor—but now Haakon knows the truth. His entire marriage was a lie. The woman he knew as his wife was no victim, but the dreki herself. And when he finally tracks down the deceitful princess, there will be a reckoning of passion and glory....

She came to him on a storm...

Long ago, Árdís gave her heart to a mortal man, despite knowing it could only end in tragedy. When her clan summoned her home, she had no choice but to leave—or see her husband pitted against her vicious cousin, Sirius. 

When Sirius insists upon a betrothal that will help him gain the dreki throne, she is forced to flee—straight into the arms of the now-ruthless dragon hunter she once called husband. But can Haakon ever forgive her deceit? And can she save him from a spurned dreki prince who would see them both dead?
