I'll try to keep this review short and to the point. This review will be for the complete series and not the individual novel(s).
It's been a while since I read an apocalyptic series, and I try to limit my exposure to them since they tend to really mess with my head, but I had an opening in my schedule and wanted some sci-fi(ish) after reading the Harry Potter series. I'm not sure how I stumbled across Brett Battles' Project Eden series, but I'm glad I did. As a story arch, the idea of a secret global organization hell bent on destroying civilization is not unique, viral infection killing the world is not unique, and having ragtag group(s) of individuals trying to stop Evil, Inc. is again, not unique. Despite this, Battles' Project Eden is a well written, and a complete look at how all of these tropes could be combined to create a story arch that is eerily believable (to a point).
Without repeating other well written reviews/summaries, I would like to offer what I liked about the series. I really enjoyed the various perspectives/point-of-views various events were written in. It was interesting to see what the various characters thought and responded to various situations, while at the same time being offered a look at how the opposite end also responded to the same event(s). This back and forth look into the thought processes and point-of-views of various characters offered a more complete picture of the action(s) taking place. There was a few occasion where this became a bit confusing and the story drag a bit, but those instances was few and far between.
I also like that there was no single hero or villain, but a cast of characters that we got to love, know, and even hate. This approach to offer various characters ample space to grow into themselves was a welcome change to other books series I've read. This character building approach not only offer the reader a more complete understanding of various character motives, but also gave them a more realistic feel to them. For instance, by the end of the series, my imagination gave Pax the look and feel of a middle-age Sam Elliot. Oddly enough, he was the only character that I put a recognizable face to, all others where ambiguous faces, but something about Pax made me give him Sam Elliot's face.
I did have some complaints, mostly technical ones like satellite phones working deep within buildings or underground, but this was mainly due to the knowledge I gained on sat-phones after reading Eccentric Circles. I also had issues with the way people responded to the shipping containers once they began to operate. I felt as is the government (both local/state/national) responded a bit hap haphazardly when it came to them. Sure they would explode if they were messed with, but I believe that the real life folks within our government would have likely opting to bombing/detonating them as opposed to allowing them to spew out its content unhindered. If not exploding them, then setting up some kind of containment apparatus around them. One only has to look at how today's law enforcement responds to a mysterious package found on the street post 9-11, with your average bomb disposal unit not short to step in and attempt to defuse any mysterious package regardless of what they know about it. This might be well wishing on my end that our government would be more proactive, if not more rash in how they would handle the situation, but was nonetheless in my forefront thought process as I read the chapters that contained the way people responded to the shipping containers. That being said, this is Battle's world, so real world mechanics might not translate exactly as they might in Project Eden's world.
Overall, I really enjoyed this series and spent many sleepless nights enthralled in its pages. I am now a new fan of Brett Battles, and now working my way through his Rewinder series, after which I his Jonathan Quinn books will shortly follow.
