When Mei arrives at the beautiful home on Arrow Island, she can't help feeling relieved. She's happy to spend the summer tutoring a rich man's daughter if it means a break from her normal life - her needy mother, her delinquent brother, their tiny apartment in the city. And Ella Morison seems like an easy charge, sweet and well behaved. It may not be the most exciting job, but at least it'll be drama-free. Or so Mei thinks. What she doesn't know is that something is very wrong in the Morison household. Though Mei tries to focus on her duties, she becomes increasingly distracted by the family's problems and her own complicated feelings for Ella's brother, Henry. But most disturbing of all are the unexplained noises she hears at night, the howling and thumping and cries. Mei is a sensible girl. She isn't superstitious; she doesn't believe in ghosts. Yet she can't shake her fear that there is danger lurking in the shadows of this beautiful house, a darkness that could destroy the family inside and out... and Mei along with them.
