I never much cares for the timothy Zahn Thrawn trilogy, and I thought Mara Jade was a bit of a Mary Sue character. But I loved the Han Solo trilogy by A.Crispin, and a big part of that was Bria Tharen. Bria was a former cult member and victim of a Hutt scam who turned her passion towards the budding rebellion. I won't spoil the ending of the last book, but she plays an important part in the overall Star Wars story.
Now, she's being erased like the rest of them, and that sucks.
