It's Peretti's ultimate monster story. And this time, the monster is real. Miles away from the hectic city, Reed and Rebecca hike into the beautiful Northwestern woods. They're surrounded by gorgeous mountains, waterfalls, and hundreds of acres of unspoiled wilderness. But something—or someone—begins closing in on them. Something no human has ever seen. And it's killing everyone in its path without remorse. Bestselling author Frank Peretti has sold more than 12 million copies of his books in print about angels, demons, and dragons. That was just the warm-up. From the master of suspense and supernatural thrillers comes the season's hottest page-turner. Be warned: this monster's got teeth.
