Heir to the philosophical-fantastical tradition of Borges, Calvino, and Perec, The Golden Age is Michal Ajvaz’s greatest and most ambitious work. The Golden Age is a fantastical travelogue in which a modern-day Gulliver writes a book about a civilization he once encountered on a tiny island in the Atlantic.

Anyone is free to write in “The Book,” adding their own stories, crossing out others, or even appending “footnotes” in the form of little paper pouches full of extra text — but of course there are pouches within pouches, so that the story is impossible to read “in order,” and soon begins to overwhelm the narrator’s orderly treatise
