Blood Brothers (The Sign of Seven Trilogy, Book 1)

In the town of Hawkins Hollow, it's called The Seven. Every seven years, on the seventh day of the seventh month, strange things happen. It began when three young boys-Caleb, Fox, and Gage-went on a camping trip to The Pagan Stone. And twenty-one years later, it will end in a showdown between evil and the boys who have become men-and the women who love them.
