The Problem Child (The Sisters Grimm #3) 10th Anniversary Edition

The fairy-tale detectives set out to rescue their parents in Problem Child, the third book in Michael Buckley’s beloved New York Times bestselling Sisters Grimm series—featuring illustrations by Peter Ferguson.

For Sabrina and Daphne Grimm, the latest in a long line of fairy-tale detectives, there is one mystery they want to solve above all others: Who kidnapped their parents?

Sabrina finds the secret hideaway of the Scarlet Hand, the sinister group of Everafters who are holding her parents captive, and she has a chance to rescue their mom and dad. But her plan is foiled by the most famous fairy-tale character in the world. How can a human child defeat a magic one? With the help of her little sister (who is a lot tougher than Sabrina realizes) and a long-lost relative, Sabrina finds a powerful weapon . . . but discovers that magic comes at a high price.

Millions of readers have fallen in love with the Grimm sisters' adventures. The books are ideal for middle-grade readers, but enjoyable for anyone who loves a good fairy tale twist.
