The Shadow Girl of Birch Grove

When foster teen Jane Williams is invited to attend elite Birch Grove Academy for Girls, she thinks the offer is too good to be true. It is.

Soon she starts receiving threatening messages from an unknown enemy. She's also beginning to suspect that the pale elegant headmistress and her gorgeous sons are hiding secrets. Lucky is the sunny, golden son who is especially attentive to Jane, and Jack is the dark, quirky older brother, who constantly puzzles her.
The longer she stays at Birch Grove, the more questions she has about the disappearance of another scholarship girl and the headmistress and her family.

What will she give up and what risks will she take to stay in this privileged world and be bound to Birch Grove forever? What's Jane willing to sacrifice for this once in a lifetime opportunity?
