This was a kindle freebie which I would gladly have paid for. It does get good reviews on Amazon (I only get freebies with plenty of reviews by people who don't just have one review posted IYSWIM 
).
A really unusual thriller with just a touch of science fiction. It appears to be the authors first novel and I'll definitely be looking out for his next. Lots of scientific and Mathematical references which will appeal if you are interested in science but needn't put you off if, like me, you aren't.
