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.
