Witch Blade, The; The Douglas Trilogy II:

Maggie Douglas had a new and full life. The lonely years of her life at Whitehall Priory were a fading a memory. Betrothed to the handsome, eldest son of a Highland Laird, she should be happy—was. Kenneth Sutton was a memory, a bittersweet memory, but nothing more. She'd found a new love. Everything was as it should be...until Kenneth returned to Scotland.
