Jeremy Spencer never imagined the occult order he and his boyfriend, Bowyn, started as a joke in college would become an international organization with hundreds of followers. Now a professor with expertise in Renaissance music, Jeremy is drawn back into the world of free love and ceremonial magick. The old jealousies and hurt that separated him from Bowyn eight years ago no longer seem significant. Then Jeremy begins to wonder if the centuries-old score he’s been asked to transcribe hides something sinister. With each stanza, local birds flock to the old mansion, a mysterious fog descends upon the grounds, and bats swarm the temple dome. During a séance, the group receives a cryptic warning from the spirit realm. And as the music’s performance draws nearer, Jeremy realizes it may hold the key to incredible power—power somebody is willing to kill for.
