Suddenly Meredith was mesmerized by his bronzed, muscular form, and her body surrendered to the fantasy that Geirolf Ericsson really was a Viking from a thousand years ago, sent only to pleasure her.

Viking Unchained by Sandra Hill

ONCE A VIKING....
He swore he'd travel the earth to find his little boy. But Viking warrior Thorfinn Haraldsson never counted on traveling through time--and he's more than a little surprised to find himself in modern day Baghdad in the midst of a Navy SEAL operation. Luckily, the SEALs include his cousin, who takes him Stateside. And there, at a bar, he stumbles on a woman with an eerie resemblance to his cheating wife...

... ALWAYS A HERO
For almost five years, single mom Lydia Denton has mourned the loss of her Navy SEAL husband. Then she meets a man who looks a lot like her lost love. Despite Thorfinn's ridiculous accusations that she's taken his son, Lydia finds it impossible to ignore the steamy chemistry between them. And as she gets to know this handsome Viking, she can't help but wonder whether two souls, separated by time, have found their way back to each other.
