From the back cover:
Mountains move hundreds of miles overnight!
Fez placed in mortal danger!
Sentient bed chased by metal-eating monster!
Amidst an already-strange world which has been turned inside-out, Fez, the Wizard of Time Travel, faces the ultimate choice: cease to exist and set the universe right, or seek his long-lost daughter and allow the universe to destroy itself. You are Fez's only hope for survival! Only by fulfilling a set of ancient prophecies can you enable the wizard to remain alive and be united with his child.
Fez VI: Wizard's Dilemma is the sixth and final chapter in the unique and popular Fez series, which places you in situations never before experienced by fantasy role-players. In a universe where anything is possible, you can meet talking mice, appear on a game show, be harassed by a smart aleck minah bird, and even serve on a jury while one of the Fez authors appears as a gorilla and is brought to trial!
