When fifteen-year-old Nate Watson moves to Windsor to live with his mysterious Aunt Celia, the last things on his mind are witches and magick and ancient vendettas. While Nate focuses on building a new life for himself and his younger brother, making new friends and adjusting to a new high school, he can't escape the feeling that something isn't as it seems.

Nate's search for answers leads him to a forbidden, locked door in Aunt Celia's mansion. Inside, he finds a witch's workshop full of mystical artifacts, some dating back to the time of the earliest Puritan settlers. It's no coincidence that Nate is now living in the very same town where, forty-five years before the Salem witch trials, Alse Young was hanged as America's first witch.

Could magick be real? Nate remains skeptical until he picks up the witchfinder's serpent--a powerful, demonic bracelet that wraps itself around his arm and permanently imbeds itself into his flesh. Now Nate must confront the truth about Aunt Celia's unlikely ancestry--as well as his own. And with her help, he must find a way to remove the bracelet before the serpent's previous owner returns--an ancient and powerful enemy who will stop at nothing to get it back.
