When Megan met Carter Anderson at Harvard, their college romance took a mystical turn thanks to The Alchemy of Will. This book by Dr. Allen Fincher gave them the power to do almost anything, but with disastrous results. Years later, their six-year-old daughter, Caitlin, is dying a slow death from bone cancer. Dr. Fincher's book offers them a cure: they can save the life of their first-born by sacrificing the life of their second. But Megan and Carter don't have a second-born... yet.

Only half-convinced, Megan, confined to their New York apartment, begins nine months of hell, and she and Carter enter a spiral that consumes more lives than they could have ever conceived. Ranging from domestic terror to all-out supernatural horror that flecks the American east coast with mangled bodies, Descending Lines takes a gut-wrenching question--how far would you go to save your child?--and turns it into a fast-paced journey to places where even nightmares fear to tread.

Descending Lines: The only way out is down.
