I'll throw in my appreciation for this series as well. I particularly enjoy the battle sequences in these books, he does a good job of weaving together various points of view and making them both engaging and relatively easy to follow. My only real issue about this series is that the individual books can sometimes be a bit repetitive, but the overall story is interesting and I never feel put off from reading. If you enjoy the first few books (the first three form a sort of mini-trilogy if you want to think of that as a starting point) you will probably enjoy the rest of them as well.
I've actually been considering doing an Aurora game loosely based off this series once C# comes out.
