True Grime, by Natasha Deen, focuses on the adventures of a teenage fairy cop named Pepper Polly Pebble Petunia Powder Puff...but don't ever call her that unless you're her partner Harley Hands! Pepper and Harley, two hard-working Grime cops, work to keep magical creatures from misusing their magic. When a high-tech bomb set by terrorists turns Pepper into the world's first fairy amputee, however, things get personal. Pepper and Harley go undercover as humans to keep the very same terrorists from destroying all of humankind by unleashing a Violent Illness of Unusual Resistance and Strength (V.I.U.R.S) in one of the human world's biggest shopping centers. The mission, however, ends up being tougher than Pepper had expected, what with the fancy new technology of the terrorists and the unpredictability of humanity.
