What if some people started to develop superpowers but they all became villains. This is a underdog story of 'normal' quest to join a team to fight back and seek revenge. 
 Brandon Sanderson is know for his world building and well thought out magic systems. None of the superpowers seem unbelievable and work within the laws of our world physics, with one or two exceptions. 
 The plot starts and shifts back to being formulaic but things never turn out the way you'd expect. There were several twists and while I saw some of them coming none was a real shocker. Characters are the standard team setup, many stereotypical but each had heart. 
 If you like superhero stories this is a very interesting alternative take. If your into urban fantasy or curious about the genre this would be a good introduction.
