Your Murder Next, by Ravena Guron 
 
From the bestselling author of This Book Kills comes a deadly new YA thriller of murder, mystery and mind-blowing twists. Perfect for fans of Holly Jackson and Karen M. McManus.

When the most popular girl at Myra's new school is found frozen to death in a walk-in chiller, wannabe journalist Myra is sure of two things:
1. Scarlett was murdered.
2. One of Scarlett's friends is to blame.
So she infiltrates the popular clique's world of envy and backstabbing to prove it. But then a strange boy holds her up at gunpoint in the woods, claiming he's killed the killer. Who is he, who did he kill...and who will die next?
