In the shadowed streets of San Francisco, October "Toby" Daye—a half-fae private investigator with a talent for trouble—finds herself pulled deeper into the uneasy balance between the human world and the dangerous Kingdom of the fae. As old loyalties fray and ominous forces stir, she must navigate treachery, magic, and her own uncertain place among two worlds. Dark, witty, and richly atmospheric, this installment blends urban fantasy suspense with sharp emotional stakes.
