Kennedy lives in her safe little world with her mother, her best friend, her cat named Elvis and a room full of art supplies. But one day after her cat runs away, Kennedy finds herself in a graveyard and everything changes. Her mother dies mysteriously and Kennedy sees things that shouldn't be there - ghostly things. When brothers, Jared and Lukas Lockhart show up, Kennedy is drawn into a world of paranormal spirits and the Legion - a group of five seemingly unconnected individuals with ghost hunting skills being passed down from generation to generation. 
 Kennedy isn't the most likely person to become a ghost hunter. She's content with her life. Her mother loves her and makes her pancakes. Her best friend Elle takes care of Kennedy's social life organizing group outings and double dates. Her dad might be out of the picture and her boyfriend may have recently broken her heart but over all - things are good for Kennedy Waters. And then a ghost tries to kill her and her mother is murdered by a demon. In many ways this book feels like it's trying to pick up the Supernatural TV show vibe but it misses the mark with me. 
 Unbreakable reads a little young at times. Kennedy is seventeen but someone could be forgiven for thinking she's several years younger for most of the book. But she does grow up - somewhere between first meeting the girl in the white dress and joining the Legion - and the story gets more enjoyable. 
 The rest of the characters are fun to read. There are the Lockhart twins, Lucas and Jared, both with an interest in Kennedy, the technological genius Priest, and Alara - the privileged goth girl who bankrolls the adolescent ghost hunters. Each come with their own unique set of skills and interesting back stories for the reader to discover as the novel unfolds. There's interesting plot that develops but at times it felt unplanned and hurried. The way the teens find each piece of the puzzle often felt bizarre and almost accidental. The love triangle felt convenient and not a situation where I cared which way Kennedy decided. 
 Overall this is an interesting read but I won't be continuing with the series. I didn't feel emotionally involved with what will happen next nor with the characters themselves. In many ways I felt like this book was trying to imitate the first season of Supernatural the TV show but fell a little short.
