Ida learned to fly from her father, and she never wants to be anywhere but in the sky. When her brother finds an ad recruiting women pilots, Ida makes up her mind to apply. The WASP (Women Airforce Service Pilots) program will change Ida's life--because it gives her purpose, because it gives her a way to help her brother (currently MIA in the South Pacific), because she has to pretend to be white. Ida has grown up as a light-skinned black in 1930s/1940s Louisiana, and now has the chance to pursue her dream of flying, though passing means denying her darker-skinned family. 
 It's a good story about a little-known footnote to WWII, and about racism, and about the ever-popular topic of Overcoming Adversity. In that regard it's an excellent choice for Summer Reading. But it does get a little History Lecture sometimes, dry and over-explain-y in the history, and slow moving, and that's going to turn kids off. (Also many historically-appropriate uses of the n-word will make it a challenge to get past parents.)
