His Highland Heart (His Highland Heart #1)
Willa Blair

Along with two other Munro lasses, Muireall Munro was taken by Clan Ross raiders nearly a month ago. She's yet to be claimed as a Ross bride. Still, after two failed escape attempts, her hope is waning of ever seeing her home and the younger brother she was raising. But the stranger who pulls her from the surf will change her life forever.
If Muireall reveals who she really is, the delicious man who just saved her life will want nothing further to do with her—yet she needs him if she is ever to escape her Ross captors. If Euan reveals who he really is to the woman he saved, he risks not only his life, but his clan. Left with no choice, can they save each other while they fall in love?
