Pitol is a true master, and these are incredible books. The words that currently come to mind to encourage you to read them feel inadequate . . . I will simply say that you should experience them. You will be better for it.
We excerpted two essays from The Magician of Vienna at The Quarterly Conversation: you can read them here. And BOMB magazine excerpted The Art of Flight. Read that here. (I am linking to the Google Cache page, as something appears off with the actual webpage.)
And here, for good measure, is a photo of Pitol and Bolaño together. It was taken on the occasion of Bolaño being awarded the Romulo Gallegos Prize for his novel The Savage Detectives. (You should also read TSD, if you have not already done so.) Pitol, a member of that year’s jury, awarded him the Prize.
