Welcome to Nocturne Falls, the town that celebrates Halloween 365 days a year. Jayne Frost is a lot of things. Winter elf, Jack Frost's daughter, Santa Claus' niece, heir to the Winter Throne and now... private investigator. Sort of. Jayne takes Sinclair on a much needed visit to her winter wonderland home, the North Pole. She wants him to see what her royal life is truly like. She knows the protocol and regulations that define her existence as heir to the Winter Throne aren’t for everyone and worries that it will be more than he wants to handle. All seems well until a weird coincidence in a toy contest has some of the citizens of the North Pole giving Sinclair the side-eye. He’s a necromancer, and not everyone is okay with that. Jayne vows to prove his presence and the apparent cheating are unrelated, but digging deeper uncovers all kinds of strange occurrences that only complicate things and make another perfectly clear. Someone doesn’t want Sinclair around. When that someone cracks and takes action, Sinclair is in danger of losing more than his good name. Can Jayne chill the rumors that threaten the royal family and keep Sinclair from being permanently iced?
