From the Diary of Agnes Jaeger: The Secrets of Silver Leaf A

Now living in a home filled with spider webs and books so old they might crumble, Agnes is thrown into the wolves' den of upper society. As a mid-semester transfer at Ore Tree's Silver Leaf Academy, Agnes must adjust to her new circumstances that unfortunately include vicious bullies and strict customs she doesn't understand. To make matters worse, her aunt is obsessed with a secret but refuses to share, her classmates are disappearing, and inexplicable incidents keep occurring. Can the rumours of a cult be true? What mysteries are hiding under the polished halls of her new school?
