The following discussion includes spoilers for this book.
I like learning more of Louis Wu's background, but I thought pulling him into the Puppeteer fleet, giving him a child, and kicking him out with his memories removed, all before the events of Ringworld, damaged my suspension of disbelief.
I thought the writing of this book was perfectly adequate, if not to the standards of Niven in his prime.
