The Mystery of the Dancing Lights

Mysteries are Elizabeth Coderre's life, and after wizards, hags, artificers, vampires, kobolds, genies, and killer kittens, she thinks she's seen everything.
She's wrong!
And when she goes to Riding Thorpe summer camp, which is built on an old government experimental facility, she discovers that there's a lot she doesn't know.
Can she solve the mystery of the dancing lights, save her friends, and escape a time loop? Or is she cursed to relive her friends' deaths forever?
Includes a brand-new murder mystery novella by Jen Desmarais starring Kennedy Fairfield (from "Assassins! Accidental Matchmakers") about her 1995 summer vacation in Baker.
