Calamity By: Brandon Sanderson
Calamity is the third book in the Steelheart series. In this book the Reckoners travel to a new city called Idithia. Without giving to much away you find out what calamity is and why its there and you also find out a lot more about Prof and his powers and about Megan. Also this book is different from the first two. The first two kind of have the same plot where they go to a city and have to kill the main Epics but in the third on there is a major twist in it and I loved it. I thought this book was awesome but I would still say that the first one is my favorite and then Calamity and then Firefight. I would recommend this book to anyone who read the first two and who likes stories about superheros and superpowers.
