Like the others in this series Caleb and the marines can’t catch a break… well actually they catch all the breaks then are immediately slammed with another but kicking problem. Over all I enjoyed it greatly. A few times I nearly put it down because one word … Valentine… She’s a good annoying villainy like character. I was every happy when she was confronted for her crimes and then was left thinking … Well of course she did. Like I said a solid Sci-Fi thriller and I plan to continue the series.
