Something evil grows in the heart of Bill Weston. He's a man of the West. He knows it -- its land, its people, its stories. It was where he had plied his trade, hunting men for money. His life had never been easy -- even before Colorado -- but it had been predictable. That all changed when he met Sister Mejia on his way to meet death in the town of Millwood, a town with a terrible man at its head and a terrible secret at its heart. Weston has faced ancient evil before, but can he do it while retaining what's left of himself, and save a young boy from the same fate? Fight the darkness within, or succumb to the darkness without.
