Eleven-year-old Micah has no interest in moving out of her grandfathers house. She loves living with Poppop and their shared hobby of driving around rich neighborhoods to find treasures in others trash. To avoid packing, Micah goes for a bike ride and ends up at Finch House, the decrepit Victorian that Poppop says is Off Limits. Except when she gets there, its all fixed up and theres a boy named Theo in the front yard. Surely that means Finch House isnt Off Limits anymore? But when Poppop finds her there, Micah is only met with his disappointment.
By the next day, Poppop is nowhere to be found. After searching everywhere, Micahs instincts lead her back to Finch House. But once Theo invites her inside, Micah realizes she cant leave. And that, with its strange whispers and deep-dark shadows, Finch House isnt just a house its alive.
Can Micah find a way to convince the house to let her go? Or will she be forced to stay in Finch House forever?
