Hi all. Don't want to be a pirate, but I'm in desperate need for some new reading. I read mostly classics on my Kindle, so no great harm to legal rights and that kind of nonsense. For now I'm looking for Joseph Konrad collected works in *.mobi. Can't really afford them - time's hard on me now. Can anyone recommend a source? Via PM maybe? Please.
