She's his enemy. But he can't stop fantasizing about her. When a sunny time traveler gets on the wrong side of a grumpy Viking, could his anger turn to passion?

Surfing in California, yoga instructor Cathy tries to reconnect with the memory of her comatose fiancé. When a strange woman hands her a golden spindle, the vegan yoga teacher is tossed into the sea of time and emerges on an English shore in 878 AD, smack in the middle of a battle between the Anglo-Saxons and the Vikings—one of whom looks just like Brad.

Viking warrior Andor is burdened by guilt over the wife he failed to protect. And he's ready to join her. So he's grateful when a beautiful Valkyrie comes to take him to Valhalla. But why does she keep calling him Brad?

Desperate to get back home before Brad's parents disconnect his life support, Cathy convinces the grumpy Viking to take her to York, where she may be able to return to the twenty-first century. Needing her help, Andor agrees with one condition: he will not protect her.

From escaping pagans hungry for a sacrifice to outwitting the English army together, the two grow closer during their journey. But when passion flares between them, will it be Andor or Brad who holds Cathy's heart?
