The Scot’s Betrayal by Keira Montclair

Alex Grant is back!
A warrior with a wounded heart.
A lass in desperate need.
Will destiny be on their side in Scotland’s War of Independence?
Destiny sent the famous warrior Alexander Grant three grandsons on the same day, at the same time. Or so the story goes. Alasdair Grant, one of the three, struggles to believe he has any special purpose. The future has never seemed bleaker for Scotland—or for Alasdair’s own family. And yet, he cannot help but wonder if fate has reached for him at last when his grandsire sends him to MacLintock Castle to help Emmalin MacLintock, the very lass who has possessed his thoughts
Emmalin would have been laird of her castle had she not been forced to marry a controlling English baron. Her heart longs for a different life, a life in which she leads her people and a handsome, strong Highlander stands by her side. A Highlander like Alasdair Grant. When the baron dies unexpectedly, Emmalin is relieved, but that feeling quickly fades when an English garrison shows up to storm her castle. Worse, there’s evidence someone in her life might be in league with them.
Alasdair and one of his cousins arrive in Emmalin’s hour of need, giving Emmalin a glimpse of what life might be like with him by her side. If Alasdair can open his wounded heart to Emmalin, it will bring him one step closer to his destiny, but he’ll need to have faith in himself—and in Scotland—to do so.
