The plane, of course, is a major character as well. It's hard for us today to understand how enthralling the idea of flight was, since flight today is more like an annoying bus journey instead of a glorious "slipp[ing] the surly bonds of earth". Like cars, planes were a luxury, but also an obsession. Even my five uncles managed to pool their resources in the 1940s and bought a small plane, which they would land in the field by the family dairy!
This was definitely more of a young adult novel than one for middle grade readers; the tone is a bit more introspective and sad.
Peyton has written fantastic books about British life for a long time-- her 1967 Flambards is considered a classic, and my daughter's favorite book is her 1994 Snowfall. Sadly, for British society, these books usually show how hard it is to keep together these grand estates. Teens who got caught up in their parents' obsession for Downton Abbey will find this a distracting read, which will hopefully get them to investigate other books set during this period by authors such as Sayers, Christie and Waugh.
