Cloaked Crimson

"Marylinn Jane... Easy prey for a hungry wolf. Lonely, quiet...weak."

Marylinn Jane is a high school student in a small, suburban town named Crooksbury. Few friends and an introverted book lover, she spends part of her time alone. She always felt content about her life and had plans ahead of her. Then, she notices small changes in her school, a girl disappeared for one day and returned to school. Eventually, several other girls disappear and reappear the next day, their expressions changing. One day, these girls approach Marylinn and ask her to meet them at a tree in the woods. A strange, eerie feeling fills Marylinn, but she decides to go.

I guess you could say this is a twist on Red Riding Hood.
