I had some time to spare and nothing to read ; I bought this on a nearby FNAC store (sorry Amazon people!). I finished it two days later, not because it was so gripping that I could not put it down, but because I wanted to get it over with, fast.
So, take some historical and medical facts. Twist them as much as you need to fit the story you have in mind, regardless of any kind of scientifical approach.
Ad a pseudo scientist ("enigmalogist" if you can believe it!) who's so smart that he figures everything out all by himself. Pour the lost soul of a mummy fresh out of her sarcophagus... et voilà!
I should have known. On the back cover is the usual "praise for" list, the fisrt one of wich is from Clive Cussler. Well, it's just the same kind of crap (minus the boasting about any and every kind of engine ever put on a car or a plane).
In fact, the only thing this book coul be good for would be as a scenario for a cable TV movie, or, for French readers, a sunday afternoon M6 movie.
