What an amazing book!! 
 I'm a big fan of dystopian novels, but this one really took my breath away. 
 The world is like any other dystopian -destroyed by war basically - but because that destroyed the world, humans have now decided to take a new approach. 
 PEACEFIGHTING. 
 Which basically is one plane from one country fighting against another country's plane. They pilots don't know what they're fighting for, but mostly it's about laws being pushed through, or rights being bought (like oil rights for example). The winning plane wins whatever their country has asked of the other. It is explained really well why peacefighting is so much better than countries going to war with one another and I really loved the concept of it. 
 But of course, not everthing is as perfect and wonderful as it first seems. Our MC soon descovers that most of what she believed in is in fact based upon lies. So who can Amity trust? And what does she need to do to stop the ones destroying everything she worked for and believed in as a peacefighter? 
 Our 'villian', John Gunnison is the leader of the Central States, one of the countries in this new world. And he is basically trying to take over their world by using Astrology -> This I found very cool, as it is explored really well and you get why someone might think Astrology can be a great weapon for taking over the world. Johnny explains himself by saying he is trying to bring Harmony to the world - even if that means he has to fight others to bring them that Harmony (kind of contradicting himself here, isn't he?) 
 Our MC, Amity Vancour, is a peacefighter and she is extremely proud of her job. She tries and does the best she can for her country. I felt like Amity was a very strong, determined character, but she is also afraid of getting to close to others. Throughout the book you find out why, and along with that, a lot of childhood memories and secrets are revealed throughout the book. 
 I loved seeing parts of Amity's childhood, as the flashback really felt like I got to know our MC more and more. And I understood her relationship with Collie and with her father (Whom died when she was eleven) a lot more after reading all of those memories! I loved peeking into her history, but sometimes it was very sad to find out so much about Amity's past. It's not that she's had the roughest life, but some stuff really made me feel for her. 
 As for Collie... Collin Reeds is Amity's lost childhood friend. They meet again after not having seen each other for four years on the Peacefighters base, finding out both of them became peacefighters. It doesn't take long for the romance to blossom, although Amity is very scared at first. She doesn't want to get to close to people, for fear they will hurt her. 
 "...and he was insane if he thought I'd ever let myself risk being so shattered again." 
 But the become a couple (no spoiler, trust me) and then... I sort of constantly thought Collie was acting a little weird. Collie has been absent from Amity's life for the last four years, but I didn't find out much about those past four years, although near the ending of the book (literally the last chapter) there is a hint about what Collie's been up to (Spoiler: (view spoiler)[ There is a hint given by Gunnison about someone that's been helping him called 'Sandy'. And Amity later reveals that Collie's nickname in first grade had been 'Sandy'. HOW SUSPICIOUS HUH? (hide spoiler)]). Although I did sort of see it coming during most of the book, it still left me curious as to what's going to happen in the second book? I'm so curious to find out what will happen to Amity, and Collie and their world. Broken Sky really left me wanting more answers! 
 SO 
 I loved this book. It's been a great read for me and I highly recommend it to people that like dystopian books! Broken Sky particularly feels like it takes place in the future, and yet this future has a 1940's fibe to it, which was awesome! 
 Just... go read this wonderfully entertaining book!
