If there was a way to save a loved one from a terrible disease, would you take it? What if the consequences were unclear? Alistair Rain’s life is fading before his eyes. His wife, Eliza, is being taken from him before her time, her body ravaged by an inoperable plague. Desperate, he turns to prayer, the last bastion of hope, but God doesn’t exist. Not in Alistair’s world. What answers is something else entirely. Something far beyond his comprehension. Something that will irrevocably change his life and the lives of those around him forever. Sin is a dark horror from the mind of Matthew A. Clarke.
