This is my first Heinlein read and I'm not sure how to describe it. Scientifically fascinating (star charts and impressive detailing of the future) and sexually disturbing (in a good way as far as the family structure goes, but maybe not so good due to the rape and its less than serious consequences). While the plot seems a little aimless, I'm still pondering the concepts about artificial humans, interplanetary governments, and gender stereotypes that Heinlein explores in this book.
