Tempted by Her Outcast Viking (Shieldmaiden Sisters #2)

Brynhild had once been close to Erik—until he'd betrayed her, and she'd hoped never to see him again. Now the fiercely independent shieldmaiden needs Erik's skills to rescue her sister. Striking a truce with the tough, isolated loner, they reach a mutually beneficial deal: help her and, in return, she'll help him in his quest to find a wife—by teaching him how to please a woman in bed!
