Personaly, I've never read the X-wing books, but I hear they are good and I olan to read them soon.
I, Jedi is definatly one of, if not my favorite SW books.
I've never read Courtship of Princess Leia, but I've heard it's great.
Never heard anything about A Forest Apart.
I already said the Thrawn Triliogy is great.
Jedi Academy books are really good also. Well, they are really good if you like Exar Kun(I like him myself), or else you might want to read I, Jedi and skip the first two because it gives pretty much the same stroy from another person's point of veiw in about a hundred fifty pages.
