This book was an emotional roller coaster I was in no way prepared to go on but wow, it was worth every second. I got it at the middle school library and was expecting it to center around the girl who died (Mattie but I thought she was Sadie at first) but it was more about Sadie getting revenge on her sisters murderer. My heart dropped multiple times throughout and I don't recommend if certain topics are sensitive for you but if you're fine with that then I recommend wholeheartedly
