The Ringworld Engineers (Known Space Series) Book

Like its predecessor, Ringworld, I really liked the overall ideas of this book: a massive, artificial, circular world that needs saving, varied hominid species filling all ecological niches, non-humanoid alien species that act in a truly alien manner, and a hodgepodge group of heroes. However, the main character, Louis Wu, is portrayed as God's gift to any female hominid; if it's anatomically possible for him to sleep with someone, he does, basically. The Ringworld revolves around sex between species, known as rishathra, using it as a way to cement trade agreements among hominid clans. Again, female characters are subpar, prone to hysterics and sleeping with Louis. The only female character who is not completely one-dimensional still sleeps with him multiple times and is portrayed as being rather masculine (she has a beard). Overall, the book was mostly entertaining and had some interesting evolutionary and engineering ideas, but I got so sick of Louis Wu, Sex God, that I finished reading more out of obligation than interest.
