I think it was better than I expected in some areas. I loved the fighting and thought they were nicely written. Both the ground and space battles. I'm curious as to the goal of the invading aliens, what they seek and why and not to mention who they are.
I think Sorilla was a great character and I enjoyed her scenes. However I'm not a fan of dual, or in this case multi POVs and there was a lot, so I have subtracted ½ a star from my final rating. I can deal with a few POVs sometimes, but they were literally all over the place and galaxy. It helped that they were relative short. I'm very interested in book 2, some day.
