The new tenants have a terrible secret. So do the landlord and his daughter...
Ever since Lucy was two, she's been on the run alongside her mother. She's never understood the reason for a lifetime of paranoia, aliases, and lies. All she understands are the rules: never lock eyes with strangers, never let down your guard, and always be ready to move on.
Finally, after thirteen years and eleven states, their next hideaway seems perfect. An isolated, fortresslike place in the New Hampshire woods is the new home they share with its owner, a gentlemanly pianist, and his lonely daughter, Gretchen. She's Lucy's age and soon becomes Lucy's first real friend.
But Gretchen and her father have secrets of their own-and an obsession with puzzles that draws Lucy into a terrifying new game of hide-and-seek. Lucy's dark past is about to come calling. And this time, for her and her mother in the house on the hill, it might be too late to run.
