A lonely orphan, playing the role of the daughter in a house of strangers. A boy who doesn't know his strength, and perhaps never will. A mother holding the cracks of their home together. In a world where women are considered to be superior to men, Arabella is adopted by a mysterious family, that seems to know nothing but mistrust and secrets. Arabella was taken in for one reason, and one reason only-in a house full of boys, there must be an heir to the esteemed Hallow family. Katherine Hallow treats Arabella as if she were her own from the start, as if she's all that matters-yet something sinister lies beneath Katherine's sweet smiles, and coos of delight-her vows to protect and love the young orphan almost seem more like a threat. Despite having brothers that seem to loathe her, and the eerie silence of the mansion, all seems well. But when Arabella discovers a boy in the attic who refuses to speak to anyone and chaos starts to have its fun, hidden truths about her new family start to come to light, moving relentlessly towards the final, most deadly secret.
