Wookieepedia to the rescue!

Here’s a list of all the EU/Legends books in timeline order (with that particular link going to the Rebellion era section). You can filter out different types of books (junior novels, etc.) at the top.

Unfortunately, that doesn’t really address your question of good books set in that era. I haven’t read most of these (only Shadows of the Empire and The Truce at Bakura, only the first of which I recall being particularly good), so I can’t really vouch for their quality.

I really enjoyed the Hand of Judgement duology by Timothy Zahn. It focuses on a group of renegade Stormtroopers and Mara Jade between EP4 and 5.

I, Jedi but you gotta read some of the X Wing series first. Some of the best descriptions of what happens inside the mind of a Jedi when using the force are in this book.
