Cassie Larchmont's summer is just beginning, and when her friends finally arrive at Lake Solaria to begin their vacation, everything seems perfect. They've even made a new friend: Nicole Morgan, a girl that's eager to share a secret. There's a hidden toy-room in an old house, one that has dolls, paints and puzzles; everything to keep little girls busy. But it's not what it seems, and Nicole isn't too happy about sharing Cassie's friendship with Diane and Lisa.
Karen Lewis is surprised to receive a call from her estranged brother's partner, especially when said brother disappeared some time ago. Eager to learn more of his life, and perhaps even gain insight into his whereabouts, Karen agrees to visit the bed and breakfast she's apparently now partly in ownership of. If the rural town of Fallen Trees wasn't remote enough, the odd business her sibling was working on is even more isolated, and something within it seems restless.
