Grr. I had a 3 paragraph review written here and then closed the tab accidentally.
1 - Yes, I'm reading this book again. Despite being written first, it comes pretty late in Larry Niven's Known Space chronology.
2 - Since his Fleet of Worlds books have only been written in the last few years (and more are to come), some of the facts and characters in this book are a little 'off' since we know about them from other books.
3 - Rereading anything will make you understand it better. This was a nice refresher before continuing on to the 4th Ringworld book: Ringworld's Children.
Rewrites are never as good as the original, so I didn't even try. Sadface.
