I'm in a bad mood and don't have a descriptive review in me. Basically, Lily (I can call her Lily because she interviewed me for a story once) provides a bio-history of the 1960s and early 70s space program from the point of view of the women married to the astronauts. The wives always had to be perfect and patriotic, and any display of insecurity or anger could threaten a husband's job and what assignments he might get. Indeed one astronaut did get fired after he left his wife for a Susie. (Susie was a popular name for Cape Cookies, it seems.)
Lily's style of biography seems unusual. She does extensive interviews with her subjects and strings their stories together into one omniscient narrative, even taking on the voice of the time period, with words like "terrific" and exclamation points employed more often than I assume is typical to Lily's other publications. As a librarian, I want footnotes and an index in any piece of nonfiction, though I acknowledge the former would be a flow-kill.
As I recall I wrote in my review of Lily's first book, one of my favorite things is how Lily takes to her older lady subjects. A gorgeous and vibrant young thing, formerly a gossip writer, she really seems to love and strives to understand them and their stories. It's sweet.
