Empire of the Saviours — A.J. Dalton

In 'Empire of the Saviours', the People are forced to live in fortified towns, their walls guarded by an army of Heroes. Several times a year, living Saints visit the towns to exact the Saviours' tithe from all those coming of age. When a young boy, Jillan, unleashes pagan magicks in an accident, his whole town turns against him.
