Midnight Revelations — D. McEntire

The chosen one…with no choice at all.
The Watchers, Book 3
Suma lives life on the edge -- in more ways than one. As her tribe's chosen protector, her role is far from a privilege. It has sentenced her to a life of isolation, shunned by the very people she is sworn to protect. But protect them she will, no matter what the cost to herself.
When she discovers the gorgeous hunk she's been eyeballing is actually a vampire, she doesn't hesitate to mark him as the next evil creature she has vowed to hunt down.
There's a Rogue-killing black wolf loose in a local state park, and Rayne is not too happy to be pulled away from his Watcher Cell in Louisville to check it out. The simple investigation turns complicated when he realizes the wolf is a female Skinwalker. And that Skinwalker is Suma. How does he know? It takes one to know one.
And when they cross fangs, another fact hits him right between the eyes -- she's his mate. Even though their passion runs hotter than the magic burning under their skin, in the end there's only one real choice.
To answer the call of love…or the call to duty.
Warning: Gruesome battles, dim-witted rogue vampires and awesome sex with real fireworks.
