Italo Calvino's Invisible Cities is certainly not a standard, typical fantasy book. Not an epic with
wizards, dragons and barbarians. But it's the best piece of fantasy
fiction I've ever read - even better than Borges' "The Aleph", which
comes in second place. At each chapter, Calvino pushes human imagination
to its furthest boundaries, challenging the reader's concepts of
reality, history, ethics. I just can't stop reading it over and over.
