Locked

Some secrets are so strong that all you can do is lock it up and throw away the key. But what if you lock up yourself instead?
Grace Starling is a 15 year old who has been arrested 5 times. Her parents can't cope anymore. She is sent to a boarding school where people like her go. She doesn't belong but someone she meets can teach her how to. Grace thinks he's too good to be true. However, he is part of a group of people, who disappear every Friday night. Who aren't quite normal. But when Grace's only friend goes missing, she must decide wether to lock it up and throw away the key, or unlock it and find out why happened that late, Friday night.
