I haven't been reading many Star Wars books since the prequels came out. Before then I was a big fan of A.C. Crispin's Han Solo Trilogy, Steve Perry's "Shadows of the Empire" and Timothy Zahn's trilogy.
I recently started reading some new Star Wars books, specifically set between episodes III and IV. "Lords of the Sith," is the best I've read in a long time. Many Star Wars books get too caught up in describing the politics of the Empire. This book gives you just enough context and gets moving. Lots of action and you get to see the Emperor and Lord Vader in a new light - hunted by an early pocket of rebellion that is ruthless because it has to be. If you are looking for something to tide you over until the Force Awakens, this book is a great choice. — Ian S., Communication
