Francis Hardinges critically acclaimed novel - out now in paperback. In the underground city of Caverna the worlds most skilled craftsmen toil in the darkness to create delicacies beyond compare - wines that can remove memories, cheeses that can make you hallucinate and perfumes that convince you to trust the wearer, even as they slit your throat. The people of Caverna are more ordinary, but for one thing: their faces are as blank as untouched snow. Expressions must be learned, and only the famous Facesmiths can teach a person to show (or fake) joy, despair or fear - at a price. Into this dark and distrustful world comes Neverfell, a little girl with no memory of her past and a face so terrifying to those around her that she must wear a mask at all times. For Neverfells emotions are as obvious on her face as those of the most skilled Facesmiths, though entirely genuine. And that makes her very dangerous indeed
