It's a three book series. It has a prequel, which adds little to the trilogy. It's highly awarded. It's interesting in that it was originally written in Chinese and it's uncommon for a translated book to make this big of an impact in sci-fi circles. You see it a lot in space conversations because it covers planetary gravity in an interesting way.
