Blood Feather

A stereotypical invitation to a dull girl to a prestigious well-known school in a stereotypical story, but that's only if you look at the outside. Eleven year old Lucy opens her front door to find an acceptance letter to Michael Junior High, a school she never applied for. Rumours fly wildly in town about the school, some saying that it is a prestigious school for famous people or royalty, or maybe a prison, in disguise as a school. One of the darkest rumours say that, those who enter the gates, never come back alive. Mysteries are singing out, and that's something Lucy wouldn't refuse for the world.

Except she didn't want to go back to school, or have to deal with people. People who could hurt her again. Weighing the two on a scale, she chooses mysteries, risking exposure to people who could break her heart all over again.

The credit for the title goes to @greatblueheron for her amazing creativity and willingness to find it.
