Ha! To prove I don't have ALL Star Wars books - I enjoyed these books. I know some folks think Bria is a Mary Sue but I found her much more believable than Mara Sue - I mean Mara Jade - and I don't think she's more important to Han than Leia is.
That said I did find it hard to believe she just happened to be involved with the Rebellion - but overall I enjoyed these books about Han Solo's early life.
