Matt (NEVER call her Matilda) has gone through a succession of foster homes before arriving at a Quaker household in a small town in Pennsylvania. Tetchy and withdrawn, she has made sure no one will get to know here because bitter experience has taught her she’s safer that way. However, when violence threatens the peaceful activities of those for whom she is beginning to care, she has to decide whether to hide away from the bullies who have plagued her entire life, or stand up to them and bring their abuse to an end.
