Nice! There are so many books out there, and I don’t know what in the SW universe you’re particularly interested in. I found ‘Luke Skywalker and the Shadows of Mindor’ to be a fun read, and it has some of the better characterizations of the OT characters. The new trilogy, ‘Empire and Rebellion’ seems promising. I’ve only read the first book, ‘Razor’s Edge’, which focuses on Leia pre-ESB, but I really enjoyed it. I believe the second book is out, which focuses on Han. If you’re a Han and Leia fan, definitely read Tatooine Ghost.
Again, there’s so much to choose from, and I’ve only read a handful myself, but take those into consideration! :)
