Locked deep in the mind of Analise Crawford is the location of the last piece of the map to the Gates to Hell and the key to unlocking it. Five years ago, to protect this secret, she injected herself with a serum to erase her memories.

She remembers nothing of her decree to protect humanity from the darkness, nor that The Firm, a secret cartel of demon loyalists, has been sent on a mission to collect her. However, vivid dreams of shadowy men, broken stone tablets, and strange encounters with familiar, but unrecognizable, faces awaken her curiosity and set off her paranoia.When a clandestine Firm tracker locates Analise her estranged family intercepts, bringing her back to a vicious power struggle between light and dark. As Analise slowly regains fragments of her memories, she tries to piece together answers to the two big questions: Where is the last piece of the map, and why am I charged with protecting it? In the meantime, The Firm is closing in on a source of leverage, a still forgotten secret—her daughter.
