The Trouble with Demons (Raine Benares) (Book:3)

For seeker Raine Benares, a demon infestation on the Isle of Mid couldn't come at a worse time. Already fighting the influence of the Saghred, a soul-stealing stone, Raine discovers she is also magically bonded to a dark mage and a white knight, two dangerous and powerful men on opposing sides.

Turns out, the demons want the key to unlock the Saghred. As a seeker, Raine should be able to find it first. As the axis of light and dark powers, she's a magical cataclysm waiting to happen.
