Star Wars: Legacy of the Force: Betrayal: Book 1

Gets you hooked on this series. You can definitely see how it all goes back to that dreaded mission in Star by Star. The Dark Nest starts his (Jacen's) slide and well, you just see how it goes after that. I've read the series and now and going back and rereading it and putting it into the context of the others makes you see how this fall is probably worse than any of the other Skywalkers'.
