The Pack. The Chronicles of Jonathan Crowley, #3

The town of Serenity Falls has a history of the unspeakable. One man unearthed it. He paid the price. So will all who fail to heed the warning... Something is coming to Serenity Falls, something that has already touched the town with its demonic power. A young girl is horribly tortured, a boy becomes a conduit to hell, the dogs of the town turn feral. One man-a stranger to the town but not to the powers of darkness-has been enlisted to stop the encroaching evil.
And soon he will discover that the true horror lies not with those who walk the earth, but with those who lie beneath it-in the damp, dark graves of the restless dead...
