The Devil's Knight (Bound in Darkness)

A dangerous destiny. . .

On the battlefields of Norman Britain, Tristan DuMaine cheated death countless times. Now he only wants to live a quiet life at his borderlands manor. But it will take an otherworldly power -- the bite of a vampire -- to unleash his fiercest appetite for revenge after a band of brigands forces him into a sham marriage with a rebel spitfire.

A heart of fury. . .

She watched Norman invaders murder her father; now beautiful Siobhan vows to avenge him. At Castle DuMaine she imprisons her sworn enemy in a marital power play designed to betray his allegiance to his cousin, Henry II. But the insatiable bloodlust that flows through Tristan's veins will soon ensnare them both in a hungry passion that inhabits a dark haven where secret desires live forever. . . .
