Midnight Blood

Carly moved to Redmount 6 months ago, suspicious of the eerie activity everyone portrayed. She suspected it was just a sickness, and soon attended Redmount High.
Carly then met Raea and Maddison, her only two best friends she could trust. She also made friends with Annise, Alex, and Izzy, but they all acted like the other citizens in Redmount.
Things then start to get creepier. People and pets are disappearing and everything seems more dead than usual.
That's when bad things start happening at school. Not bully bad. But blood bad. A trail of blood leading to the old locker room only said one thing.. There was a murderer in town.
Charity Nirvera went missing a few weeks back, only to be found in the back of a pickup truck, dead.
Kyle Yoyo also went missing, never to be heard from again.
All grown ups and kids who went missing were either mean to others, or of commited something horrible. A "sin".
All three girls are then charged with the murders of their dead friends, and only one takes the blame.
They have to find out who this cold blooded murderer is.
Or their lives are on the line.
