I am going to be honest here. It took me about 4 tries to really get started with this book. I would make it a chapter or so, then put it down. Again and again. But one day, I sat down and it finally clicked. The Killing Jar ended up being a really good story, and I am glad that I (finally) read it! 
 The first 5 chapters or so were definitely slow. The set-up of the story was necessary, but not exactly exciting. We read about Kenna's first experience with her powers, and the lasting affects that it had on her. We learn a little about her mother and her twin sister, who is very sick, and her best friend. And we learn that Kenna is a gifted musician. It is after a music festival when the story gets going. And once it starts, it becomes a truly interesting and unique story. 
 Kenna is unique. She has an unusual power, one that she hates. And she feels like she is alone in the world. She has her mom and her sister, but she is always apart. Blake, her best friend, is the only person who makes her feel... like she might deserve a chance at happiness. Just when they make a step towards a different relationship, a horrendous event occurs and Kenna's whole world changes. She learns that she is not alone after all. There is a community of people, hidden, that are all just like her. After the event, her mother drops her off with these people, alone. At first she is resentful, but then she starts to finally feel like she belongs. She has a family. She has friends. But once she is told she has to make a decision, she decides that she needs to know the truth about her new family. What Kenna learns will change everything for her, for the rest of her life. 
 Kenna was a really well-written and relate-able character. I felt for her, and I rooted for her. There were times I wanted to kick her butt. Every character in the book plays a unique and crucial part to the story, and for Kenna. I was impressed with Jennifer Bosworths characterization with not only Kenna, but also with the secondary characters. She spent time with them, and truly paid attention to their roles in the story. 
 The world-building, as well as the details of this new ability, were done very well. There was a lot to this story to keep my interest, once I got past the initial bumps in the road. There were some hiccups here and there, mostly in the pacing, but I can honestly say that I did enjoy The Killing Jar. I would recommend it to pretty much anyone who enjoys stories with special powers! 
 Thanks to the publisher for sending a copy of The Killing Jar for me to review. This in no way had any bearing on my opinions.
