First, the thing that I thought after listening to the audible the author made a small talk on Veteran who committed suicide and gave a number for a person to call not many authors do that and really impressed me as a Veteran myself.
Can things get any worst for Max, he thrown out if the military then by the CIA which later in the book it was another frame up as it was when he was in the Marines. For ever step forward he gets knocked back 20 nothing goes right and people get killed both good and bad and he has to live with the death of his wife and son in a car wreck or was it murder? Before his final couple missions something has gone wrong in Mexico he loosen both two if the hostages and his men and the party who hired him tries to not pay him till he finds out his brother in law was behind the taking of the three women and one was his wife who was the only survivor and was able to verify that her husband tried to have her killed or sold into slavery with her two friends.
The main story is not about humans but aliens who crashed here before the ice age. This is a very sad story of a young man 19 years old and dieing of cancer and bloody because the whole team of mercenaries are slaughtered and in addition the team of security, doctors and other staff at the crash sight if the alien ship. Thus part of the story I want go into but I highly recommend you listening to it by the end you will feel tears for those who died who was innocent and a young man who makes a great decision about his life and the truth of Max wife and sons death. But at the same time you feel relieved to find the ones who really caused the suffering met their end in a way we all hope we never will.
