Now I'm not sure if this is considered piracy or not, but I guess if it is, it can be taken down. But it has been on the Witcher forums for a while and hasn't been deleted, so I guess it's fine.
These are the fan translations of the book (pdf, mobi and epub versions)
(from: http://en.thewitcher.com/forum/index.php?/topic/20967-our-community-fan-translations/)
The Sword of Destiny (pdf, mobi, epub)
Times of Contempt (pdf, epub. No mobi, and they removed the epub version for some reason, so I put the one I uploaded)
Baptism by Fire (pdf, mobi, epub)
The Tower of Swallows (pdf, mobi, epub)
Lady of the Lake (pdf, mobi, epub)
They don't include the ones that have been officially released in English. Which from what I've heard, the official translations aren't aalll that great, but it doesn't bother me.
So far I've read The Sword of Destiny, The Last Wish, and a bit into Blood of Elves. I have really enjoyed them so far. Though they do have their dark and sexy moments, there was a lot more humor and playfulness than I expected which I didn't mind at all.
If you wanted to read all the books as a whole, the first one to start with would be The Last Wish. Even though it came out after The Sword of Destiny, apparently it has stories that happen before it. Though I could have sworn there were some stories in The Last Wish that happened after The Sword of Destiny...Whatever the case, it doesn't really matter which of those two you read first. The rest that are listed above are in their proper order, with the exception of Blood of Elves which is before Times of Contempt.
So in short, the chronological order is:
- The Last Wish
- The Sword of Destiny
- Blood of Elves
- Times of Contempt
- Baptism by Fire
- The Tower of Swallows
- The Lady of the Lake
(I put a little effort in this post mostly because I was bored.)
