What is the setting of The Surrender Tree: Poems of Cuba's Struggle for Freedom by Margarita Engle?

The setting of this book is Cuba in the nineteenth century. Although the setting is one country, the characters do find themselves located in different parts of this island nation. Rosa, Jose, and the other rebels spend much of their time in caves and the jungle. Much of Rosa's writings describe her surroundings and the plants she uses to create medicine. She often speaks of the musical quality nature has and its ability to conceal and protect.
