The Scot’s Deception by Keira Montclair

They must trust each other—or bear the consequences.

Chrissa Grant isn’t the sort of lass who enjoys sitting at home. With a pivotal battle looming between Robert the Bruce and the English, she knows exactly where she wishes to be: fighting with her older cousins, the group known as the Highland Swords. So when she’s given the chance to take part in the war effort, she eagerly accepts, especially since she’ll get to work with Drostan. The two have practiced side by side for years, dreaming of the day they’ll finally be able to defend their clan.
As they embark on the most dangerous adventure of their lives, Chrissa and Drostan’s friendship turns into something deeper and stronger. For Drostan, it’s a dream come true—he’s loved Chrissa almost as long as he’s wanted to be a Grant warrior. But a dark force is gathering around Clan Grant, and it threatens to swallow them up.
Chrissa and Drostan’s ability to survive depends on their faith in each other, and they mustn’t fail. The fate of Clan Grant hangs in the balance.
