No bests. I have my favorites, but which one to choose? Some are meaningless without the rest of the series, some were incredibly interesting back then, but aren't as great on further readthroughs...

The book thst changed my life the most is probsbly "What is seen and what is unseen" by Fréderic Bastiat.

The book that I enjoyed the most is probably "Zelená" (green) by Martin D. Antonín. (A great quirky fantasy book about goblin engineers)

My all time favorite is tied between the "Hitchhiker's guide to the galaxy" by Douglas Adams and "Dobrák" (a good guy) by Jiří Kulhánek. (An apocalyptic novel where one day out of the blue aliens show up and abduct most of humanity and turn the rest into some sort of zombies)

Damn, I feel like naming 20 more now that I started to think about it. Don't ever ask people to choose just one book. That's torture. :D
