This is a very exciting and interesting book. It's about an 11 year old girl that lives with her grandmother, Dr. MacKenzie or Dr. Mac, because her parents died in a car crash when she was 7. The book is about Maggie who is having trouble with her grades in school, and she is banned from the clinic until her grades go up. On top of that, since she can't do the work if she's banned, some kids from school help out at the clinic. She feels like she doesn't belong there anymore. Plus it's worse when her cousin, Zoe, who's mother is an actress comes to stay. The story is about a man who is running a puppy mill which is illegal. He sells sick, dirty puppies at the farmer's market. Maggie, her cousin, and "friends" try to stop the man from selling the pups. It's full of sad times, and good times. This is a good book if you love puppies.
