Things to know before you download/read: This new series is based on the Extinction Cycle series. Some say that you will be all right reading this as a stand-alone series. I believe it's helpful to get a full background on the characters and the situations they've been through, so I recommend investing in the Extinction Cycle universe. If, however, you are sensitive to violence and adult language then perhaps you should forego all the books.
As any good soldier knows, never underestimate your enemy. However, when you have limited resources you have to make decisions based on the information you have available. It's also human nature, to find a way to survive and thrive despite the odds. That's how this story begins but things quickly change as those years of looking up are now tainted by an unexplained shift in the status quo.
I think the authors did a wonderful job of showing the strength and resilience of humanity while at the same time shaking things up like a snow globe. The reader gets to see where the glittery flakes fall.
