I picked this book up hoping to make sense of all the senseless acts that have occurred in this country since April 20th, 1999. The tragedy that occurred at Columbine High School over 20 years ago was senseless and a preventable act of violence. Dave Cullen's reporting on the events leading up to and after the incident is remarkable. I thought I knew what happened all those years ago, you grow up hearing about it and seeing the different documentaries and news stories but I think most get it all wrong. Cullen pushes the envelope and reveals information that isn't widely reported. 

This book brought me to tears multiple times and took me a while to read because I needed frequent breaks. I appreciated the focus on the survivors and the families of the victims. I would challenge anyone who doesn't support gun reform or law enforcement reform/defunding of police to read this book. I was appalled to find out nothing has changed in the 20 plus years, and even worse, no real action was taken after this horrible incident. 

(Obviously this book is VERY triggering and should be read carefully)
