Billy Hooten is a weird kid. He gets beat up a lot, and spends the rest of his time doggedly trying to build a robot. One day, Billy Hooten hears a cry for help coming from the cemetery that borders his backyard. Against his better judgment, he runs toward it. And after that, everything changes for Billy Hooten. Because Billy Hooten, you see, is Owlboy. A quickthinking, goggle-and-feather-wearing superhero who protects the bizarre and monstrous citizens of Monstros City, a city that exists under Billy's hometown of Bradbury, Massachusetts. But is Billy truly worthy of the moniker Owlboy?
One day, using the magical passage that will take him to Monstros City, Billy forgets to close the door to the crypt, and is followed by . . . Victoria. Oh, no . Victoria is Billy's neighbor, his constant shadow, and a huge pain in the butt. Worse, Monstros City seems to exaggerate the traits people have in Bradbury—and Victoria arrives in Monstros with something that Billy and Archebold name the Destructo Touch. Owlboy is supposed to protect Monstros City—but has he just introduced the agent of its destruction?
WHAT’S SCARIER THAN the Sassafras Siblings and Rot-Toothed Hopping Monkey Demons? The answer, my friends, is old people. And Billy is forced to face his fears when his family picks up his Great-Aunt Tilley at Shady Acres to bring her home for the long weekend. Meanwhile, in Monstros City, a mysterious villain unleashes a legendarily destructive monster: the enormous Zis-Boom-Bah. Zis-Boom-Bah has the inhabitants of Monstros so riled up that the military wants to use the OMG (“oh my gosh!”) device, which will destroy Zis-Boom-Bah, but take half of Monstros with him. But Billy has a revolutionary idea . . . which leads him to a realization about the scariest Old Person at Shady Acres . . .
IN THE FLOCK OF FURY, Billy Hooten learns the strange—and horrifying—truth behind Monstros City’s woes. It turns out that all the supervillains Billy has encountered are under the hire of a super-SUPERvillain called the Monarch. The Monarch hates Billy—and with good reason. But when Billy learns the Monarch’s shocking true identity, will he be able to fight back against his most powerful foe yet?
