She was his lifemate, the most important person in his world, and then he forgot her.

After enduring torture at a demon's whim, Adrius is left with shattered memories and a beautiful woman who claims she is Nyah, his one true beloved. With the help of a special fae ritual, he remembers who he is-and how much he needs to prove himself to secure his lifemate's heart once more.

A miracle brings Nyah, true Queen of Vampires, home after an eternity in the Fell Lands. She and her people are unlike any the world has seen; they are shifters, embracing a deep connection to animal spirits for survival. The only thing missing in Nyah's pristine realm is a king, but upon reuniting with her lifemate Adrius, she realizes he's no longer the man she tragically parted with so long ago.

When Nyah's utopia is threatened by the darkness unleashed on Earth, Adrius swears he will do everything in his power to save it. Will he succeed when faced with the same evil that broke him once before?

His heart depends on it.
