This book I'd classify as a light reading exercise, not one that requires a deal of mental effort. It is, to me, reasonably sound in its plot lines. What I find difficult are the thoughts that many of the characters have. Those thoughts seem to be rather shallow and repetitious. Having said these things, though, I'll readily admit that it is far superior to any work of fiction I could put together. My star rating is on how I compare this effort to all the other books I've written reviews about. Recommended as light reading.
