Answer:
Muffin by Susan Cooper is a children's book about a young girl named Daisy living in England during World War II and how she was bullied.
Daisy was cornered by "Fat Alice", the ring leader, Pat and Maggie, her cronies on Monday morning. Maggie shoved Daisy against the rough fence and a splinter got into Daisy's arm.
Daisy was asked to walk the line and she couldn't do it properly because she was terrified, the three girls descended on her and began to pull her blonde braids and scrape her head against the asphalt.
The attack on Daisy was relentless and she tried fighting back but was unsuccessful because Mrs Walker saw her trying to kick at Fat Alice's knees and chided her, threatening to report to her teacher. That moment, an old lady and her dog walked in to defend Daisy stating that she wasn't at fault that she was only trying to defend herself from her attackers.
Daisy eventually went back to class and Mrs Walker didn't report her to her teacher. Daisy smuggled a piece of meat and on her way home, she stopped by at the old lady's house and asked if she could feed the muffin. The old lady answered in the affirmative.
The bullying in school continued for Daisy even after reporting to her teacher, she decided to ask for the old lady's help. The old lady welcomes her into her house, gives her tea and biscuits and promises to talk to her teacher about what she saw. However, a bomb hit the old lady's house and she was killed, but Muffin survived and Daisy started taking care of it.
The similar traits all three- The old lady, Muffin and Daisy- have in common is compassion and justice.
