 Startide Rising, by David Brin, is: - a SF novel - The second book in the Uplift Saga (I just read and reviewed Sundiver) In this book, a starship with uplifted dolphins (mostly), humans and an uplifted chimp made a huge discovery, and now a lot of alien enemies are after them. They go to a quite interesting water planet to hide for repairs.  This book is from the early 80s, and sometimes it feels like it. Thankfully, the big ideas are more important and shine through the rest. Middle felt a little slow, but the conclusion was satisfying enough. There is a very mild connection with book 1, Sundiver. No need to read it first, nor would I recommend reading it - it was just ok.

 Sundiver, by David Brin, is a SF novel and part of his original Uplift trilogy. In Sundiver, Earth has met the galactics, and there a ton of them, in constant war except for some institutions such as the library, that contains all they know (supposedly). There is barely any research - it is considered bad to not just look things up in the library. Now humans and a bunch of alien go dive into our Sun, to make contact with living sentient creatures there. Chaos ensues. Overall, good, considering it is a 1980 book. In SF sometimes being old is super obvious, sometimes not. This one is in the middle. The Uplift part - where almost all sentient life in the galaxy is uplifted by a patron, which usually gets 100,000 years of slavery (ouch!), is interesting. In this book, mankind has already uplifted chimps, and is working on dolphins.
