Book — John Marrs

They say every house has its secrets, and the house that Maggie and Nina have shared for so long is no different. Except that these secrets are not buried in the past.
Every other night, Maggie and Nina have dinner together. When they are finished, Nina helps Maggie back to her room in the attic, and into the heavy chain that keeps her there. Because Maggie has done things to Nina that can’t ever be forgiven, and now she is paying the price.
But there are many things about the past that Nina doesn’t know, and Maggie is going to keep it that way―even if it kills her.
Because in this house, the truth is more dangerous than lies.
