Substitute post-apocalyptic for dystopian and a male protagonist for a female one and this book is similar to other mediocre YA fiction. There’s not much of a sense of drama or urgency considering this is about survival after the long dormant Yellowstone volcano erupts. The minor characters are interchangeable parts, and the writing isn’t exactly stellar. The story line is plausible and did keep me interested but mostly contains characters that are either catatonic or ready to shoot on sight. Overall not entertaining enough for me to continue with. I’d say unless you are heavily into this genre of YA to pass on this one.
