I picked up the first book in the series as a filler until I could find something better. Well turns out I didn't have to wait long, maybe 3 pages and it only got better with each installment. Through out the series, our protagonist, Capt Lee Harden was one of several men in secret underground bunkers all around the country. They are trained to emerge at a specific time when called upon to assist in the rebuilding of the nation in case catastrophic events brought it to its knees. After several false alarms it happen, he just didn't expect it and certainly not the way they had anticipated. The Omega Virus was released, creating crazed, rabid individuals who had no thought other than to kill an eat those that were not infected. While not mindless Zombies, they were still less than human. This was never in the books of what might happen, a pandemic of sorts maybe but not like this. When he is cut off, unable to receive any transmissions from his contact, Lee emerges from the bunker albeit earlier than he should. From the beginning Lee did his job, he helped people, protected them as best he could, kept them safe even when they were ungrateful, unkind and in many instances deceitful and treacherous. He made friends and he lost them. Some he came to trust, others he tolerated. And always he is a soldier with a mission driven by duty to his country and to the remaining population, helping to defend against the hordes of infected and those who would do harm to others and take what they want. When the very people he tried to help betray him, he is understandably angry, resentful and downright P.O.'d. But even those he could deal with, and he does. It is (spoiler) those that he has come to call family, the ones that call him 'traitor' and send assassins to kill him that hurt the worst. After being he is shot and left for dead a device entrusted to him to help the few desperate remaining is stolen from him. Before he fully recovers he is captured by thugs who want what he does not have. After a harrowing incident he escapes killing several of the thugs and infected. He is still duty bound to complete his mission, protect and rebuild, but first must somehow recover the device and help the people that depend on him. He is not superhuman by any means and most of the time, he only wishes for at least a couple of hours of sleep to regenerate but even that little respite is too often denied him.He continues and he perseveres because he must and your heart will break for him because he is willing to sacrifice himself, his emotions and all that he as a man is to do what he was trained to do; fight for a people and a country he loves. But with every loss, every deed Lee becomes the soldier that everyone should fear as he does the unthinkable, particularly when his friends are in danger. He does find a few he can trust and will stand by him and that keeps him going not wanting to let them down. D.J. Molles is not afraid to kill off main characters and really I would be very surprised if he didn't, after all this is an apocalyptic series with well over 2/3's of the worlds population turned into ravenous infected creatures. Not to mention religious zealots, rapist, murders and misguided people that see the infected as just a group of highly misunderstood creatures that need to be protected. And of course we have a self appointed President who is willing to sacrifice most of the population of what is left of the United States for his own gain. While there are tense moments, in particular as a small group of survivors on a hospital roof are surrounded by hundreds of thousands infected, and when Lee, Sgt Tomlin and Nate are running through the woods ahead of a large group of infected, this installment deals mostly with what has become of humanity, where even those you think you know cannot be trusted and those you don't trust turn are the ones Lee entrust his life and the lives of those under his protection. It is a battle to the end, against the hordes of infected and people that are determined to see this small group of survivors fall. Is it the rebuilding of a nation with a revolution in the works? Even that is unclear. If this is the final installment, it leaves a lot of unanswered questions so maybe there will be one final book to give us the satisfaction that is sorely lacking in this ending. And was that Sam and a progeny of Deuce patrolling, continuing....We can only hope.
