Mr. Alten can't write
This is exactly the kind of book that makes some snobbish people think that thriller-horror & sci-fi books are trash. I was enticed by the idea and I aknowledge that the writer is genuinely in love with it, but, after all , this is a book and not a made-for-TV miniseries, so should be something more than a bunch of random action scenes with no real characters or substance. And the final part is totally ridicolous ! Above all, everything is presented with total absence of writing skills (the prologue! ) .I'd just save the part with the shark chasing the helicopter . You can read this early morning ,on a crowded subway car.....
