After seeing her maybe-mobster boss murder a guy, Delaney James assumes a new identity and pretends to be a mail order bride. She finds her groom-to-be living in a town that celebrates Halloween every day. Weird. But not as weird as what she doesn't know. Her groom-to-be is a 400-year-old vampire.

In this new Jayne Frost and Sinclair Crowe mystery, a royal road trip takes the Princess and Prince Consort of the North Pole all the way to Las Vegas. And even though they’re in Sin City on official business, it doesn’t take long for trouble to find them. Trouble that’s very close to home. In fact, Sinclair’s entire family is gambling on him and Jayne figuring out what’s gone dangerously wrong with the cool new magic trick at the end of his parents’ show.

Jayne Frost is a winter elf, Jack Frost's daughter, Santa Claus's niece, heir to the Winter Throne, and now private investigator. Needing someone he can trust, her father sends her to Nocturne Falls to find out why employees at a toy store are going missing. Doing that requires getting to know the town, which leads to interesting encounters with a sexy vampire, an old flame, and an elevator that's strictly off-limits. The more Jayne finds out, the more questions she has, but the answers lead her deeper into danger.

Shadowvale isn’t typical small-town America. The sun never shines, the gates decide who enters, magic abounds, and every resident bears some kind of curse. No one knows this as well as raven shifter Deacon Evermore, who, like everyone in his family, has a curse. While his position as Shadowvale’s peacekeeper lets him use that curse for good, he’d rather live anywhere else. He stays for his family but doubts he can last much longer.

Concerned that technology is about to chase mythological creatures out into the open (how long can Sasquatch stay hidden from Google maps?), the League for Interspecies Cooperation is sending Jillian to Louisiana on a fact-finding mission. While the League hopes to hold on to secrecy for a little bit longer, they're preparing for the worst in terms of human reactions. They need a plan, so they look to Mystic Bayou, a tiny town hidden in the swamp where humans and supernatural residents have been living in harmony for generations.
