Ruhysvet is a world built on ruins. Spirits slink through the five kingdoms, pursued by the Order of Nightmares-hunters with a divine mission to purge the realm of malevolent phantoms.

Ren, a roving Nightmare, has no place to call home and has made peace with his loneliness. When he falls for a librarian whose home he was hired to cleanse, Ren sees something other than a solitary future-but as his past haunts him and a danger to the Order looms, Ren must decide if the happiness he's found is worth what he'll have to sacrifice to keep it.

Sanne Esclarmonde could have been queen, but surrendered her birthright to become a Nightmare hunter. She envisioned a life dedicated to the gods and the Order-but her hunt took her home, where she's spent the last three years serving her cousin, the king of Jasniostvo. When she discovers an ancient evil lurking beneath the palace, one that endangers everything Sanne holds dear, she must choose what to save: her family, the Order, her gods, or herself.
