Sorry, not sure if this is going to work or not, but I thought it would be worth having a thread to list when books that may be of interest are available for download, especially if they are on free deals, or bargain prices.
So, the books you probably know about:
The Mammoth book of JTR, is £4.99, but is a LOT of book for the price.
The A to Z is just £3.99, again, a lot of book for the price.
JTR: Scotland Yard investigates is £3.39
And the lesser known cheapies:
MJ Trow's JTR Quest For A Killer is just 99p.
Blood Harvest by David Andersen is a piffling 99p (and was more interesting than I expected).
The Crimes of Jack The Ripper Re-examined, by Paul Roland is also in the 99p bracket. (No idea how good it is, I haven't read it yet)
Still a lot of books overpriced on Kindle, though I think competition in the JtR field may force them down. Some publishers still insisting on equal price with hardback, etc. If you're self-publishing, a 99c price only gives you a tiny % royalty, which is much bigger if you have RRP $2.99 or higher.
