Awesome book from cover to finish. It is almost worth it to suffer through the first book. The only complaint I would have is that the 2 Yirella endings contradict each other and ends on a semi-cliffhanger. I hope Mr. Hamilton picks up that thread some day.
If you are looking for MilSciFi with a capital MIL, this is for you. If you are looking for a little story that goes with your pew pew laz0rguns, this is not for you.
wWhat a failure of a final book. 50% of the book nothing happens and then it fizzles out with the only interesting chapter being the epilogue. It is clear that the author did not know how to bring this story to an end.
