She vowed to slay every Viking who set foot on her land. Now, one stands at her side—and perhaps in her heart.

After the Callan clan lost nearly all its warriors to brutal Viking raids, the women donned armor and took up arms to defend their homeland. Fiona Callan, the Laird's daughter, is the fiercest among them—unyielding in battle and steadfast in her hatred for Vikings.

Desperate to rebuild, her father strikes a bargain with a neighboring Laird leading a mixed tribe of Highlanders and Vikings. The Callans will receive new warriors, but most are of Viking blood.

Furious, Fiona swears she'd rather die than see her clan's women marry Vikings. Yet when the newcomers arrive, led by the formidable and savage-looking Varrik, she can't deny his skill in battle—or the way he challenges everything she thought she knew.

As trust grows between the clans, Fiona feels left behind—even her own sister is drawn to Varrik's commanding presence. When an old ally offers her a way out, she must choose between old loyalties and new alliances.

Can Fiona set aside her hatred to save her people? And what will she do when her heart whispers that the true enemy might not be who she thinks?
