The Voodoo Queen, the Cheerleader, and the Exploding Girl

Jade Hill and Associates are back on the case. Mary Katherine, an eighth grader and most popular girl in the school, who would never ever be seen within twelve yards of a seventh grader (if she hadn't lost Buck Dieter's class ring), hires Jade. Jade is the only seventh grader in Bonaparte with her own detective agency. Then someone puts a spell on Mary Katherine so she's withering away at an alarming rate, and ironically, Samantha, the granddaughter of a notorious Voodoo practitioner, is expanding exponentially and just about to explode. It looks like black magic. It is, after all, beyond the realm of the real world when Jade finds herself hired by 73 dead runaway slaves to catch their murderer. There are tunnels under Jade's house and tea parties with skeletons and all manner of strange goings on, but Jade Hill and Associates are on the case and if the spells can be reversed and the wrongs can be righted, they're the team to make it happen.
