Wow! I wasn't expecting such a good book when I picked this one at the library to read with my 10 years-old son. It was a VERY pleasant surprise!
Set in the US during WWII, this is the story of Frankie (short for Franklin Delano Wattleson), a sixth grader crazy about radio shows and avid to save the world with his friend/sidekick Mario Calvino.
The book is all written in dialog form, plus the transcription of radio shows (including those funny commercials!). The style is really innovative. Although the story is funny, other more "real" situations are present, like Frankie's brother being wounded at the war (and coming back home suffering from depression), Mario's father dying while fighting the war, etc. These events are not display in an upsetting way, though.
I think this book is a great way of introduce historical fiction. I'll try more Avi's books for sure.
