Walter Jon Williams regularly draws praise for pushing the limits of the science fiction genre. His third novel featuring AR (augmented reality) games designer Dagmar Shaw, The Fourth Wall follows Sean, a washed-up child actor recruited to star in Dagmar's latest movie project. But when people on set start dying, Sean wonders if Dagmar's secretive behavior is hiding a more dangerous game. "Williams and Dagmar fans will rejoice, and it should attract the near-futurists and techno-thriller crowd as well."-Kirkus Reviews
