Fascinating fourth book in this series. While Peggy, book three, was in the style of a "schoolgirl" novel, this book was written in a romantic thriller type of novel with epistolary sections. There were quite intriguing elements to this story, beginning with the categorization of the Spaniard colonial inhabitants as the "gringos" who were oppressing the true Cubans. Rita considers herself a Cuban, even though her father was American and her mother a Spaniard. She has romantic ideas of fighting for her country, but learns the reality of war very quickly and becomes involved in the cause in ways that help her mature and evolve, making the novel something of a coming-of-age story. Rita is still an entitled and overly excitable character given to dramatic exaggeration, but it is part of her charm, and Richards certainly knows how to plot an exciting tale. Richards includes historical elements of the Cuba Libra movement and the American Rough Riders who helped the Cuban revolutionaries, and does not shy away from the more realistic aspects of war. I am quite impressed with Richards's mixing of literary styles and genres, and her use of contemporary historical elements. Looking forward to the last two books in this series.
