Marrow by Tarryn Fisher
In the Bone there is a house.
In the house there is a girl.
In the girl there is a darkness.
Margo is not like other girls. She lives in a derelict neighborhood called the Bone, in a cursed house, with her cursed mother, who hasn’t spoken to her in over two years. She lives her days feeling invisible. It’s not until she develops a friendship with her wheelchair-bound neighbor, Judah Grant, that things begin to change. When neighborhood girl, seven-year-old Neveah Anthony, goes missing, Judah sets out to help Margo uncover what happened to her.
What Margo finds changes her, and with a new perspective on life, she’s determined to find evil and punish it–targeting rapists and child molesters, one by one.
But hunting evil is dangerous, and Margo risks losing everything, including her own soul.
