Farryn Ravenshaw has spent her life chasing the supernatural mysteries her vanished father left behind, eventually crossing into Nightshade — a purgatorial city where lost souls dwell and a cold, raven-winged harbinger named Jericho Van Croix rules a decaying cathedral. Nightshade interweaves a present-day gothic mystery with a centuries-old doomed love story, revealing piece by piece why their fates are irrevocably bound.

Farryn is a tenacious investigator with a pure heart who is slowly drawn into a world of angels, demons, and inherited sin; as darkness seeps into her she must reconcile her morality with her hunger for the truth and her love for a man who is unambiguously monstrous. Jericho Van Croix is a banished, morally grey fallen angel — possessive, ruthless, and utterly devoted — whose centuries of waiting have made him incapable of letting her go.

Across two books Farryn and Jericho uncover an ancient curse — the Pentacrux — linking them across lifetimes, while descending into Infernium, a hellish asylum where Farryn's darkness grows and Jericho's devotion is pushed to its limits. The duology explores whether love can survive condemnation, corruption, and the machinery of heaven itself, culminating in an emotionally devastating resolution.
