I've read two of the three. I always wait for the paperback versions of the novels to come out, because I don't want to spend $30 on a book. Aftermath and Aftermath: Life Debt aren't perfect, but at least they have a cohesive three-act plot structure. The first third of Heir to the Jedi doesn't connect to the rest of the book at all. It feels like the author turned in the second and third act, was told the book wasn't long enough, and wrote a random first act that didn't do anything for the rest of the book except introduce a character that was killed off by the end anyway.
If the book had been a selection of three short stories in the same package, I think it would work, but as one cohesive narrative, it falls flat on it's face.
