One of my favorite books. I was pulled into the story from the first sentence. There's suspense, good character development, solid action, great descriptions, and I just love the plot. I've always been intrigued by the Yellowstone supervolcano and this book is a satisfying development of what would happen if it erupted. This is probably one of the most well-written of all the dystopias out there.I loved following Alex and Darla on their journey. They are both characters that are easy to relate to and very likeable. The plot is very realistic. I felt like I was experiencing it. This is really an excellent read.
