Solomon's Seal in Bloomington, MN

Living in upstate New York, computer salesman Colin Hampton never thought he'd have to risk his life and soul to save his family. But after being attacked by the demon Apophis and left for dead, he learns that he may be the last person able to prevent Hell on Earth.
Exorcist turned demon-hunter, Father Mitch Stackwell, witnesses Colin's miraculous recovery and recruits him into service. If they can't kill Apophis, the antichrist will start his reign ten days from now.
But someone has found the legendary ring, Solomon's Seal, and they aren't done bringing unholy monsters into our world. Armed with sanctified weapons and a mysterious gift, Colin and Mitch must stab and exorcise their way through Satan's lieutenants in a race to prevent Armageddon and save Colin's family.
