Ringworld by Larry Niven
Any of you guys reads these books.
I read the first, but was a bit disappointed.
Four stars for the first half, two stars for the second.
Began promising and really felt like it was building to something amazing, but nothing really happened.
Also, people seem to never mention the comedy in this book. Definitely has subtle hints of 'Hitcher's Guide' style of comedy.
The luck of Teela Brown.
