The Masked Man is building an army of villains from the greatest stories ever told—and Alex and Conner Bailey are the only ones who can stop him. With Alex cast out of the Fairy Council and the adults refusing to listen, the twins must rely on an unlikely team of heroes to chase the villain through the pages of Oz, Neverland, Wonderland and more. But can they outpace the Masked Man before fiction becomes a nightmare? (Book 4)
