Query: Unusual Space heme

This book is not for the lineal thinker. The author found some value in shifting back and forth between decades, but I found it confusing and frustrating. The characters are varied and interesting, the plot astonishing, and on the whole the text is well written. There are occasional sparks of clever or even brilliant insight. Point of view moves from one character to another, leaving the reader somewhat adrift. There was enough techno-talk to support the premise of space travel for the average reader. If this is a serious book (and it is), the adolescent aspect of language and smirking over sex could be toned down to advantage. I'm not quite a fan, but the book will remain in memory for a long time. Much to think about.
