Demon's Cradle

Parasitic Rider infects Devany and her loved ones, leaving its potential in their heads. Devany must find the primary host before the Rider manifests into a full-blown parasite. Amidst her search, her abusive friend's ex escapes from prison, her job is at risk, and her dad shows up with a book about a world he shouldn't know. A demon with a grudge then strips Devany of her humanity, leaving her with no desire to save those she loves.
