Bloodstone

The tyrannical rule of the Deacon and his Jerusalem Riders has unleashed upon his world a sea of bigotry and hatred, where Unbelievers and Mutants are massacred in the name of God and Peace. And the long-vanished Jerusalem Man is now considered a saint of the new order. To speak ill of his memory is heresy. But where the church in Pilgrim's Valley is burnt to the ground, its congregation slaughtered, a rider appears and hunts down the killers.
And word spreads - The Jerusalem Man is back! Hunted and alone, Jon Shannow must battle the forces of the Deacon - and face a terrible enemy from another universe: a dark god who feeds on the souls of worlds.
