Wareham continues the story begun in the WWI Innocents Abroad series. This time its mostly about Tommy Stark's son Thomas, who has been flying against Fascists in Spain and signs up to the RAF because he and other flyers had to get out of Spain after losing.
Why he went to Spain in the first place to fly for Communists is not ever clearly stated, the author is obviously leaning heavily in favor of Communists, seeing them as at worst mistaken. Everyone who opposes Communism in this book is at best a rich elitist ass and usually a flat out fascist. According to Wareham, the British military was riddled with outright fascist Hitler supporters, not to mention the government. There's only one passing mention that maybe there might be a communist in the government -- something proven in later years to be very true and many more than one.
Again, Wareham portrays the British society and government as awful, stupid, backward, elitist monsters who have to change (read: become more left wing). Its even more pronounced in this book than the last series. Thomas runs into and marries the first girl he sees in England, as does his father Tommy who has been unwed since the bizarre ending of the last series 20+ years earlier, but immediately hops into bed with a girl and marries her straight away.
Those are the negatives. In the positives, there's a decent overview of prewar England RAF, the planes being flown, their relative weaknesses and strengths (the wings on the old Hurricanes, for instance, were canvas covered, still, and they were armed with .303 machine guns that largely bounced off of German planes). Tactics and particularly getting used to the radio system in planes and how to properly use them as well as how to communicate effectively are shown.
Thomas is less rash and impulsive than his father, said father signing up to be a commander of coastal forces flying sea planes. He is otherwise a basic Wareham hero, stumbling constantly into ever greater status and wealth. This series feels less engaging and easy reading than the previous ones but I'll give it a few books to see if it grows.
