Kopernikus - after you read Pandora's Star, you're really going to want to have Judas Unchained ready. It's more like two halves of the same book; if you wait too long between them, you'll forget stuff, and it'll drive you batty.
Great duo, though; Hamilton is really spectacular.
I'm reading it as a part of a monthly reading-circle in a German SF-Board. We started with "Misspent Youth" last month (One of the worst books I've ever read, unbelievable that this is from the same author as the Night's Dawn-Trilogy) , in February and March were going through "Pandora's Star" (The Book is divided into two Paperbacks in the German translation, would have been too thick (Roughly 1500 pages...). In April and May were working on Judas Unchained (Again two halves) and in June and July it's going to be "The Dreaming Void".
