Sundiver - David Brin This was a recommendation from my husband, who read these books (The Uplift Saga) when he was younger and loved them. For a science fiction novel that was written and published before I was born, I have to say it has aged very well; this could have been written today. The technology and the science described is excellent, which was why my husband figured I would like this in the first place.

It was also an unexpected pleasure to discover as I was reading that Sundiver turned out to be a pretty decent whodunnit mystery, and the perpetrator behind it all would surprise you.
