A postmodern visionary who is also a master of styles of genres, David Mitchell combines flat-out adventure, a Nabokovian lore of puzzles, a keen eye for character, and a taste for mind-bending philosophical and scientific speculation in the tradition of Umberto Eco, Haruki Murakami, and Philip K. Dick. The result is brilliantly original fiction as profund as it is playful. Now in his new novel, David Mitchell explores with daring artistry fundamental questions of reality and identity.
