What am I?

"Who am I? What am I...?"
It is a question Maery whispers only to the dark, locked in the silent struggle of her own mind. She is no ordinary human, yet she is nothing this world has ever dared to name. To the noble courts, she plays her part perfectly-remaining a silent shadow, the lowborn, overlooked servant of Lady Alithea. But shadows have teeth. As ancient, monstrous secrets begin to claw their way to the surface, the nightmares of her mind become terrifyingly real. When the strangest situations force her hand, those who look down on her will soon realise that some servants are far more dangerous than the masters they serve. The court is about to learn exactly what happens when you push a creature with nothing left to lose.
