Emerald

Charlotte knew nothing of her parents except that they'd died when she was a child.

And when her aunt's will leaves no provision for her, Charlotte must leave the only home she's known for the uncertain protection of an uncle she's never met at his manor house, Plas Melyn.

Plas Melyn seems cold and unwelcoming, but when acts of violence that can only be directed at her occur, Charlotte has to wonder why anyone would want to kill a poor orphan?
