The novel starts out with a catchy idea, Alex, a young woman, suffering from a fatal brain tumor is in the woods for some days of peace and reflection when the USA are being attacked by EMP blasts that kill most adults between about 13 and 60. Some of them don't die instantly but transform into some zombie-like creatures.
Around the half way point of the novel there is a cut in the story that introduces a new surrounding, new people and most disturbingly a whole different pace. While the first half was constructed like a page turner, with cliffhangers at the end of chapters, a very fast pace and one moment of excitement following the next, the second half is interesting in terms of the difficulties of a dystopian civilization, there isn't much happening. The people that I grew to like except for the protagonist vanish from the story and to the end their fate is unknown. The story feels like it has no real ending, just a cut between part 1 and part 2, there are a lot of questions left unanswered. Sure it is part 1 of a trilogy, but still some answers could be dealt with...
So overall the book was a disappointment, but especially in the beginning it is a real pageturner that lays out a horrible apocalyptic world.
I would have wished for a more even pace, more consistant protagonists and a bit more closure at the end, even if there is a second part to follow.
