"I was a rat!" So insists a scruffy boy named Roger. Maybe it's true. But what is he now? A terrifying monster running wild in the sewers? The Daily Scourge newspaper is sure of it. A lucrative fairground freak? He is to Mr. Tapscrew. A championship wriggler and a budding thief? That's the hope of Billy and his gang. A victim of "Rodent Delusion"? So says the hospital doctor. Or just an ordinary small boy, though a little ratty in his habits? Only three people believe this version of the story. And it may take a royal intervention — and a bit of magic — to convince the rest of the world. Set against the backdrop of a royal wedding — with a pertinent parody of the press — here's Philip Pullman's youngest, funniest novel to date: a magical weaving of humor, fairy tale, and adventure.
