Unbreakable Heart — Kara Griffin

Love cannot resist an unbreakable heart… After losing the love of his life, Liam of Clan Kincaid, is sent in service for what his uncle considers betrayal. Liam gives himself to the battle wearied king, Robert the Bruce, and vows to mend his tarnished reputation. That would be easy if not for the lass who insists he aids her. Makenna Mackenzie has lived through hell, her home and land taken by the English. All she wants is vengeance of the man who cut off her ear and destroyed everything held dear in her heart. The only way to achieve her goal is to plead with the legendary king's guard. She wants them to train her to be a mercenary like they so she can use her sword to the fullest when she finally meets her enemy. Liam finds himself in a quandary because Makenna is not the forthright lass he deems her to be. But his UNBREAKABLE HEART can withstand her, can't it?
