Frost’s Bite by M.A. Church

He’s what things that go bump in the night fear.

Tragedy brings the ice elemental, Nicholas Frost, to America and lands him on the doorstep of the High Council. While surrounded by a group of Guardians who question his offer to kill the vampire Jackson, Nicholas stumbles across the man fate has decreed his. Although overjoyed, the secret he hides is now in jeopardy of being revealed.
Something lethal lurks within.
Cold. Powerful. Feared. A killer. Like the softly falling snow, Nicholas is silent and deadly. Always alone. Always guarded. His abilities are unrivaled, and other paranormals avoid him. With good reason.
And the man fate has paired him with is a truthsayer—a living lie detector.

Guardian Jonas Parker is convinced fate has made a monumental mistake. Guardian lifespans are practically eternal. Elementals only live a couple of hundred years. No way that golden thread which links them means what he thinks it does. Surely fate wouldn’t gift him with a man he’ll outlive?
Jonas is a truthsayer, which is difficult enough. Add in the chance of an accidental surface reading if he touches bare skin, and no one is willing to get close to him. Jonas can dig into anyone’s psyche and unearth all their secrets regardless if they’re willing are not.
No secret can remain hidden from him.

While Nicholas and Jonas struggle to figure out how a mating can work between two such different paranormals, Jackson plots. As the final battle looms on the horizon for the men of Mystic Bay, a terrifying prospect has emerged—something not even Nicholas and the others may be able to defeat.
