I agree with most of the first review, except that I highly recommend it. It could perhaps be argued that it qualifies as 'historical fiction', but then, so is very much of what actually passes for historical non-fiction-- perhaps better referred to as 'history massaged', after the fact. Not to encourage the so-called 'conspiracy theorists', but fact is that history is replete with examples of history being massaged before the fact. Whether you agree with the premise (I am still checking), fact is that it actually (to my mind, and tastes), is much more engaging than, say pretty much anything that Tom Cruise has done--because this, at least, has a very strong possibility of being not far from the truth.
