Download Calibre and you can convert almost any format (PDF, Word, Epub etc) to mobi (kindle) format. Normal sources of "ahem" dodgy downloadable content also have ebooks....
Brilliant book! The Nickel Boys is fantastic too and well worth a read if you can find a deal on it (y)
Many thanks for these recommendations! Have added both to my list :D
Ah sorry I assumed it was a Kindle deal.
I forgot to search! But this is a different format, epub, so might help people that don't have a kindle. I see also I can sort by price. American Psycho is also 99p.
