In the tradition of Margaret Atwood's The Handmaid's Tale Hendrix creates a New America, one in which women are second class citizens and all teenage girls are required to have a chaperone when they go out in public. Chaperone's are exclusively other women who have decided to take one of the few jobs available to them.
Stella's Chaperone (Sister Laura) is not averse to bending the rules for her charge. Sister Laura sometimes disappears when she and Stella are at the library so that Stella can steal a few moments with her crush, Mateo.
It is intriguing that there even is a public library in New America. But of course there are also a lot of forbidden books. Sister Laura passes some of this literature along to Stella, helpfully suggesting that she hide the taboo works between the covers of some of the other books in her room.
It appears a revolution is afoot!
