Mike Costa is a sixth-grade boy living in Pittsburgh during the time of the Great Depression. A sick grandpap, a blown-up banana factory, a bully named Andy Simms, mysterious dead hobos, dead rats littering the streets and the possibility of the family's store, Costa Brothers, going under are all problems that Mike tries to solve with the help of his best friend, Joseph Ryan.
Mike, "Rat Boy" or "Macaroni Boy", as Simms likes to call him is Italian-blooded, and cares a lot about his family. So when he discovers that his grandpap is having stomach problems, he wants to do something about it. Mike finds out that the same thing is causing not only his grandpap to become sick but the rats and hobos of Pittsburgh as well. Is it the bananas? the forbidden hooch? the Allegheny River water? the cat fish in the river? With a little help from his new found friend Old Sneaky, reliable Joseph with his cop-like questioning and a little bribing of Andy Simms, Mike finds out and helps his grandpap get better.
I really enjoyed this book, especially because it had a historical aspect to it as well as it being set in Pittsburgh. At the end of the book, there is an Author's Note from Katherine Ayres. In this, you can really see that Ayres did a great job of telling this story as realistically as possible. The things that happened during this time frame are greatly depicted. The main problem of the story is even something that was a great threat to those who lived during the Great Depression. All of her researching really added to the overall enjoy I had while reading this book.
I especially enjoyed the fact that Mike Costa was the "hero" of the story. It was nice to see that such a young boy still had his morals in tact and was responsible enough to help solve problems that could have had a great impact on his family forever. I didn't really like the whole plot of the story. It was well-written, but what actually went on in the story was a little bit bland and I thought that maybe something bigger and better could have happened, or been the cause of what was wrong with Mike's grandpap. Don't get me wrong, I did enjoy the book thoroughly, but I wish there would have been a little more adventure or a bigger climax.
I would recommend this book to anyone who enjoys reading a story set during the time of the Great Depression, and even anyone from around the Pittsburgh area. It's always kind of neat to read something that is set in a place that you live close to. I think that a lot of people would be able to relate to Mike in the way that he will do whatever it takes to help out his family.
As a future teacher, I would probably use this book during a unit on the Great Depression. I think it greatly depicts Pittsburgh as it would have been during that time, and the hardships that the Costa family encounters are ones that are historically accurate. I think that this would be a good book to read as an entire class and to have the students take home and read a chapter every so often during the lesson. You could do a lot with this book, including activities for language arts and math. There are so many supplemental activities that could be done with this book that I think it would be great for any teacher of 5th or 6th grade to use during their Great Depression unit.
