Query: Great book, very interesting world......

I like most of Clark's other work and gave this a try. It was a solid choice and I finished it pretty quickly which indicates that I really liked it. The characters are not the most interesting people in the universe, but the Rama object and mystery surrounding it were very gripping and had me anticipating each new adventure with plenty of enthusiasm. Clark describes Rama perfectly and I could actually see the images he was describing. Very well done and highly recommended!
