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's niece, heir to the Winter Throne and now ... private investigator. Sort of. When Lark Bramble, an old frenemy, shows up in Nocturne Falls, Jayne finds herself reliving the painful past and trying to make responsible decisions that won't mess up her future. But being an adult proves harder than she thought. Finally at peace with where things stand between her and Lark, Jayne thinks everything's cool until a chilling event at the Black and Orange Ball shatters that peace and puts Jayne at odds with the powers that be. She knows she's on thin ice, but she's determined to crack the caper. Can Jayne find a way to right the wrongs she might have caused or will she forever bear the guilt of allowing herself to be snowed again?
