Demonstorm (Heart of a Vampire, Book 6)

A vampire demon half-breed must save the only woman able to mend his soul. Half-demon, half-vampire, Sean MacDougal is an outcast, unwelcome by all. When the Arcaine world finds out a war is brewing that will affect all paranormal creatures, Sean is the only one who can find the demoness who holds desperately needed answers. Used for centuries as the pet Seer of the demon who destroyed her family, Mayah is rescued by a strange half-breed who asks, rather than demands, her assistance. Unable to trust, she pretends to agree, but only if he helps rescue her brother, held prisoner deep in the frozen wilds of Alaska. Becoming a protector fulfills an emptiness within Sean he never knew existed. Being protected makes Mayah feel safe for the first time in centuries. Hunted by an entire demon army, led by the one who wants Mayah back, they must learn to trust in themselves, in one another and in the emotions sparking between them--no matter how hard they try to resist.
