This was a great book, I loved the world that Kessler and Kittredge set up. I liked the way the heroes were portrayed and the slightly twisted version of a "Hero Academy" the churned out heroes that were products more then actual people. There were no secret identities for these people, the only identity they had were their superhero alias'. Another point I liked about this book was the way it was set up alternating chapters between Jet and Iridium, giving you two different perspectives and two vastly different world views, making you sympathetic to both.
The thing that bugged me was Jet, she really got on my nerves sometimes, but that was only minor. In general I liked her and all the characters, especially Iridium, they were both relatable and well written and I liked watching their relationship change as they start seeing each other in a different light.
I really enjoyed this book and I am definately going to be getting the next in the series "Shades of Grey" as I look forward to reading about the consequences of the two heroes actions from this book.
