Excellent book for young readers from the ages 10 to 15.
Reynolds Yank Interviewing the RAF approach lends immediacy. As does his contact with British civilians, merchant seamen and others.

Contains some minor errors: Oddly, he states that "Squadron Leader" Arthur Douglas was KIA when in fact Pilot Officer Douglas of 610 Sqn survived the war.

Reynolds describes meeting some members of the "American Eagle Squadron" when no such unit(s) were operational in 1940. Seven US citizens flew in the Battle (thus violating US neutrality laws) but the three Eagle Squadrons were not combat-ready until 1941.

Other glitches include P-40s and "P-37 Mohawks" arriving in Britain during the Battle. Actually, the Tomahawk/Kittyhawk never flew in NW Europe, and the P-36 was obsolete by 1940.
