I picked this up to read the story The Garden of Forking Paths, after reading Fluke which references it several times. The book actually has five short stories in, but I found the title story the most interesting and memorable. 
To me it feels like Le Carre x Sophie's World with a pinch of Piranesi. I'm enjoying that and would definitely read more Borges. I suspect I'd have to be in a mood to concentrate though, as there are a lot of ideas and weird things going on.
