Flying to Europe trying to decide what to buy on kindle for reading. What would y'all recommend? Pelagius? Tarkin? Kenobi? Thoughts?

I liked Catalyst, Ahsoka and bloodlines personally. Have heard bad things about aftermath and Tarkin but haven't read them.

I thought about those to. There's a lot of options

If you haven't read them yet, the X-wing series. They're a good way to learn about several of the pilots in the game, and fun reads (I prefer Alston's Wraith series to Stackpole's Rogue series, but that's because Corran isn't as engaging a character as the Wraiths IMO).

Plagueis and Revan are two of my favourites, along with Labyrinth of Evil.
