Hell to Pay: A Tale of the Shrouded College - Charles Soule - Bog

Married couple Maia and Sebastian Stone have entered into a deal with the mysterious Shrouded College - in exchange for magic abilities, the Stones must locate 666 cursed coins brought up from hell centuries ago, each of which can buy the services of a demon. The coins have been used by awful people to do awful things over the years, and now the Shrouded College wants them for itself. If the Stones fail, they will never be free, and the world will become a living hell. But if they succeed... what price will they pay? Collects HELL TO PAY #1-6
