Cześć parasit and welcome to mobileread ! (how do you say "welcome" in polish ? that would be a useful word to know...).
you'll find lots of sf and fantasy lovers here to exchange recommendations and discuss books with.
since you're using stanza, do you know the site feedbooks.com ? you can find thousands of free books there, and they have quite a lot of recent sf / fantasy released under a cc licence. it's accessible directly from stanza !
i completely understand not living in a house made up rubber, i have the same trouble. thank goodness we have ebooks now !! no rubber house needed.
