Kirsten's Promise is a powerful story about Kirsten's encounter with a little boy, Ezra, who's living out of an overturned wagon. Thinking that his mother will soon return, Kirsten promises not to tell anyone about the boy or the wagon. But as the days pass and the weather grows colder, Kirsten has to decide whether she can better help the boy by keeping her promise to him, or breaking it. After reading the story, girls can read about wagon trains like the one that Ezra and his mother planned to join, and can make a flower crown like those made by children traveling across the prairie in the 1850s.
