Three hundred years ago, Regan York left England, exiled from his own clan by his father. He took refuge high upon a mountain, where he thought no one would ever find him. When he met Bryn Navarro, he let the dragon shifter take control of the mountain without a fight, and he joined Bryn’s clan. No one knew the truth about Regan’s past until Bryn’s lover–and Regan’s commander–asked him. Regan swore off all relationships after his exile. He never expected to meet someone who could change his mind. Salutael is on the run. Like his demonic brethren, he possesses a strong gift, but his is the ability to counteract the diseases and poisons his fellow demons can inflict upon their draconic adversaries. Now Sal is fleeing for his life, and right into the arms of the enemy.

Mason Navarro fled his brother's clan years ago and made a name for himself as a premier fighter in an underground fight club. Dr. Shane Lawson is a world-renowned scientist specializing in vampires and various matters relating to blood. When Bryn Navarro comes seeking help, neither man can refuse him. The clan is readying for all-out war with a demonic force hellbent on wiping them out. It's going to take Mason's training and Shane's knowledge to keep them all from succumbing to the dangers of demonic blood. But demons don't play fair, and Mason Navarro is forced to make a decision: stay hidden in the closet, or save the man he loves more than life itself.

Lone wolf Korin Meyers has never told anyone his most closely guarded secret. Everything changes the moment he meets the man he's been lusting after: Beau Trainor, a dragon guard in Bryn Navarro's clan. Beau only meant to meet the wolf who'd captured his attention. He sure as hell didn't expect to discover the man is his mate. Now they're both facing a challenge they knew would come, but hadn't fully prepared for. With the Navarro clan going to war against its demonic enemies, it falls on Korin, a packless alpha wolf with a history no one expected, to lead the dragons into the bowels of the earth. The Navarro clan is hoping for the element of surprise. What they get is an ambush. Korin finally finds the demons responsible for the destruction of his entire home and his kin and he wants nothing but revenge. But what price is he willing to pay for it?
