On the night of the Leonid meteor shower, Moira Newton finds a damaged celestial being crash-landed outside her old house. She nurses him back to health and — since he remembers little or nothing of his previous life, not even his true name — calls the silent angel Leo. The ten thousand year old warrior that she comes to care about is sure of only three things from before his fall: that he has loved Moira for her entire life, more than anyone or anything else he has ever known; that she is the vessel for a secret Crucial to the survival of his entire race; and that the very sound of his voice could kill her instantly…

Intended for adult audiences, Sentinel of Heaven explores the many different forms that love can take and asks the question — how far would you go for what you believe in?
