First, let me say that I enjoyed this book and the angle that the author took. However, due to the way that it is written, I did not develop any kind of attachment to any of the main characters. This book is basically written as a narrative of events that happened, reminding me of a fictional history book. The book also gets very technical about its development of the space drive and weapons.  Liked it, didn't love it. Will buy the next one to see what happens.
