The Highlander's Welsh Bride by Cathy MacRae

It was over. Prince Llywelyn was dead, his soldiers fleeing before King Edward’s army. Carys, a distant cousin to the prince, herself a princess of Wales, had picked up arms alongside her husband more than a year ago in the fight for Wales's independence. Now homeless, her husband buried beneath the good Welsh soil, she seeks shelter in the north, far from the reach of Longshanks’s men.

It was time. Birk MacLean has been ordered to take a bride and produce an heir. He grows weary of the lasses paraded before him, women of delicate nature and selfish motives. He desires a wife strong enough to help lead one of the most powerful clans in Western Scotland.
One like the Welsh woman sitting in his dungeon, arrested for poaching MacLean deer.
Can Birk convince Carys marriage to him is preferable to a hangman’s noose? And will the heard-headed Scot be worthy of a Princess of Wales?
