Highland Surrender by Heather McCollum

With his family’s honor on the line, Norse warrior Erik Halverson has no choice but to follow the orders of the royal house of Denmark. Now he must follow his destiny—and royal command—to sail to Scotland, find his enemy’s weakest link, and abduct her. Their mistake, of course, was thinking the Sinclair lass wouldn’t fight back.
From the moment her four brothers took control of their clan, Hannah Sinclair has learned to stand tall and defend herself. So when a big, brawny, and admittedly handsome warrior tries to abduct her, she isn’t about to give in. And the more he tries, the more she’s determined to make it as hard as possible…and enjoy it all the while.
Now Norway’s greatest warrior has a Highland hellcat on his hands, and Odin help him, he can’t resist her. But with the brutal Sinclair brothers coming after them, Erik is out of options. War is inevitable. And when a man is forced to choose between duty and passion, only one will win…
