The Highlander's Arranged Marriage. Highland Legacies, #2

Iris is heartbroken. Her dear father has passed. Now her mother has promised her to a cad of a laird. What's a lass to do but run away from certain disaster and violence? Angus's entire family was lost in a horrible murderous rampage. He alone survived. Now he's got a scar, a broken heart, and vengeance on the mind. He's become a man who tends toward rage at the drop of a hat. He's not the kind of man anyone wants to be around.
He's not remotely interested in romance or friendships or socializing. On a ride with his best friend Lorne, he finds an unconscious lass.  When his best friend suggests that Angus help the lass out by marrying her, he wonders if she will runaway from another proposal and his uncontrollable rage. Iris is between a rock and a hard place. Choosing between kindness and rage and politeness and violence leaves her with few prospects.
What will Iris do now?
