The City of Seven Hills — Anthony Barnhart

The disease came suddenly and without warning. This first installment of the "Dwellers of the Night" trilogy begins with the disease's outbreak. This is a story about tragedy, despair, and hopelessness in a world thrown askew. Covering the first six months of the disease's rampage, this book explores the nature of “the dark-walkers” and The Man's struggle to preserve both his soul and his skin.
