Minerva's chapters are as follows and here is a significant quote & analysis from each. Pages numbers will depend on whatever edition you have. (Mine is the Plume paperback edition. Those numbers are here but may not correspond to your own):
Part I, Chapter 2 (11-30): "I...saw what happened to Lina and realized that I'd just left a small cage to go to a bigger one" (13). Here, Minerva has gone away to school. Her clasmate Lina has been selected among the girls to become one of Trujillo's concubines. Minerva realizes that her dream of freedom away from her home was really just another trap for women.
Part II, Ch 6 (84-118): "What's more important, romance or revolution? Both, both, I want both." Minerva has allowed herself to fall in love with Lio, and will not surrender her love to the cause completely.
Part III, Ch 12 (257-301): "Adversity ws like a key in a lock for me. As I began to work to get our men out of prison, it was the old Minerva I set free" (269). For Minerva, life must have a purpose and a cause to be worth living. Although she discovers in Part II that love is also a necessary part of her life, it is not enough to make her feel completely alive. Minerva needs to *do* something.
