Query: A great disappointment.

This story was so far from any reality, that it was hard to stay with it. I love a science fiction angle, but it's nice if some threads can be drawn to reality to make the premise seem plausible. The style of writing, also, did not resemble the previous books by this author, books which I greatly enjoyed. Frankly, it read as if a contract were being fulfilled, and much was done by ghost-writers. Sorry, but this one's not for me.
