Query: I liked this book without meaning to.

I bought this book because it has a chapter ("Jake") dedicated to my great uncle Jake who grew up and still lives in Smitty's hometown, Ponca City, Oklahoma. I thought it would be a boring, detailed WWII story, so after I read the chapter on uncle Jake, I put it away. I picked it back up and starting reading it one night when I could not sleep, thinking that it surely would put me to sleep. Wrong! I was so engrossed with seeing Smitty through his bombing missions. I felt that the generation gap vanished, and could feel the emotions that a 20 year old Smitty was dealing with, and remembering how simple my life was at 20 years old. Thank you Smitty and uncle Jake for your service.
