Ghouls. Why did it have to be ghouls?
Mindbender Lola Bragg and her two friends, were-lion Stefan and vampire Andrei, are given the gross job of cleaning the bottom floors of the Jewel Academy's library from packs of rampaging ghouls. Meanwhile they're missing out on their class's field trip to Faulkner's Island.
Lola hates being stuck in the Jewel Academy. It's a cross between a special magical school and juvie. She'd do anything to sneak out and join her class, but before she could launch a plan, the entire Junior class of the Jewel Academy has been kidnapped by merfolk. Divided into two categories, slaves or food, the students are forced by the mermen to loot the hoard of a blue dragon and keep it contained behind a magical barrier so it doesn't extract revenge on them for stealing his sapphires.
It's up to Lola, Stefan, and Andrei to save the day. But deep in the ocean, who's going to save them when things go horribly wrong?
