The Kalazad Tales Series, Book 2
Someone is stealing the villains from stories, and it's up to the girls to save them.
After saving the kingdom, you’d think Revka and her Centaur girlfriend Iyarra would have earned a nice long rest. But when they head down to the Enchanted Forest (the magical land where all stories come from), the place is run down, the natives are surly, and someone is stealing all of the villains. Turns out, that’s a bad thing.
So nothing will do except the girls must run around the forest, hunting up mad scientists, sneaking around underground lairs, and uniting with a group of rogue librarians to get to the bottom of it all. And while they’re at it, they just might be able to take a young hopeful in hand, and teach him what it means to be a hero.
