The Woman in the Wall — Patrice Kindl

And hide is what Anna does throughout the course of this amazing book. She retreats into the fabric of a big old house, building a series of passageways and secondary walls that allow her to share the life of the house unseen by her mother and sisters. As Anna says, her family is not observant. But Anna herself is a quirky and perceptive witness to the life she has chosen to escape. Then a mysterious message is thrusted through a crack in the wall, a message that gives Anna a reason to emerge.... Once again Patrice Kindl has created a magical world and an irresistible heroine.
