In the underground city of Caverna, the masters of their craft create unparalleled things: wines that erase memories, cheeses that induce hallucinations, and perfumes that make their wearer appear trustworthy to others. The people in the above-ground Caverna are more ordinary, except for one thing: their faces are blank and expressionless like fresh snow. Only the face-smiths can teach how to show or feign an emotion. In the strictly guarded cheese tunnels of this distrustful world lives Neverfell. Her face, hidden behind a mask, makes her dangerous, and it will not remain concealed forever.
