Broken Things by Lauren Oliver
An enjoyable read about a teenager murdered in the woods. Everyone thinks her best friends did it after becoming obsessed with a made-up story. But the murderer is still out there.
I did have a difficult time differentiating between the two teenage protagonists, so I never knew who was narrating. But I was intrigued enough by the similarities to the Slender Man stabbing case (where two best friends lured another friend into the woods and repeatedly stabbed her to impress the fictional Slender Man) to keep reading, and overall I enjoyed.
