This was an amazing book. The story was thrilling and held my attention until I had finished. The end felt a bit rushed when compared to the first two books in the series. It started out slowly, then went to a quick jog and then to a sprint in the pacing of the story line. They dynamic between David and the Epics was interesting. Through the interactions David's true strength is found and his past no longer holds him. There is danger at every turn for David including the dangers of just interacting with Epics even his team members. I had a great time reading this book. Most fictional books have a repeated pattern that leads to a somewhat pradictable outcome, however, this book was inventive and kept me guessing. Calamity provided an amazing end to the Reckoners series.
