I've just spotted this thread because of Spaze's post bringing it back to the top again. I downloaded the ebook then went to amazon.co.uk to read the synopsis and reviews. The first review says this:
"I got all the way through this book thinking it was very familiar. Then on turning the last page I found out why. Stel Pavlou had sold his original story to the publishers of this book who have essentially just rewritten his (badly!)
Forget this book and buy the original - Decipher by Stel Pavlou. I've read it three times now and still find it gripping."
How very strange. Are they implying that Stel Pavlou sold his book to Thomas Greanias who then carved it up and re-published under a different title?
