But Gabriel’s hedonistic lifestyle leads to an addiction to laudanum, and ends in a violent death that changes everything.
Meanwhile, scientist Melchior Croll continues his grim investigation of immortality. When he captures Gabriel, Croll discovers the key to eternal life itself. As Gabriel fights for his life in a lunatic asylum, he knows Rose is his only hope of escape. Unfortunately, a secret order of dark magicians gives her problems of her own.
As the true nature of Croll’s experiments on the insane becomes clear, Gabriel discovers his troubles have only just begun.
