Query: Well written, but you've read it before

James Hogan has been a favorite of mine for a long time. It is a real joy to read hard SF written with skill, there are not many who can combine cutting edge science with the ability to write sensible sounding dialouge and fashion believable personalities. Having said that, this one does not make it. The old 'waking up with amnesia and killers after you' plot has been around for a long, long time. Sure, there are a couple of twists, but nothing really new. The real disappointment, however, is the political layering. Anyone who likes an L. Neil Smith novel would like "The Multiplex Man". Exactly the same depiction of Libertarians as good, smart, helpfull, successfull people; and everyone of any other viewpoint as eithier naive, criminal, mentally ill, or a combo of all three.
