Quaking — Kathryn Erskine

Don't call her Matilda. Her name is Matt. And don't even think about getting close to her. She doesn't need anyone. Can't you tell by looking at her, dressed all in black with a spider painted on her face and her ice-cold stare? But most of all, do not bully her. She has been through it all already.

But everything changes for fourteen-year-old Matt when she moves in with peaceful Quakers Sam and Jessica Fox, who are active in the movement against the war in the Middle East. Soon, conflict arises in town over the war, and suddenly, no one is safe. Matt fears for her safety and the safety of her new family. Could the boy who terrorizes her at school be behind it all? And how can she save the family she is actually growing to love when her fear always leaves her quaking?
