Took me a while to finish this, but The Cyberiad is a thoroughly enjoyable collection. It's not easy to follow what's written given how inventive Lem is with language (the translator, Michael Kandel, has done an amazing job on a difficult task), but follow it I did.

I wouldn't say that this is a book to be read in one go. I'd recommend reading it in several spurts (a sally at a time perhaps) over the span of some months.
