"where are books 2 & 3 from this series?"
This is book 4 in the Ringworld Series. I enjoyed Ringworld and thought this was the sequel, but quickly became lost when starting to listen to it. I did some research and found that the 2nd book is called "The Ringworld Engineers", and the 3rd is called "The Ringworld Throne". Unfortunately, these do not seem to be available on Audible. Not sure how to rate it since my issue is with Audible and not the book - so going with 3 stars.
"no useful information"
this book is primarily a bunch of hype about how great of a person Warren Buffett is. i don't disagree that he's an impressive person, but there is very little substance to this book. there's also a lot of information about his personal life. i guess if you like hearing details about famous people's lives you might enjoy this, but i didn't learn anything useful.
"great book"
really enjoyed listening to it. highly recommend if you like sci-fi. i like sci-fi but some of the books i have gotten lately make it really hard to suspend reality because they're just too far out there. this book was right on though. i plan on finding more by larry niven.
"very good"
Best audiobook I've listened to so far. It was interesting and very informative.
