Woodruff, Elvira "Dear Austin: Letters from the Underground Railroad" - 1998
I never read "Dear Levi" which seems to be the other side of the correspondence. Therefore, I don't think we get as much information about the Unterground Railroad as there might be in the other book. But I still think this story is good for children if they want to know what was giong on and how black people lived during slavery time - and even afterwards.
Nice little children's book.
From the back cover: "In this companion novel to Dear Levi, told in letters,11-year-old Levi helps a young African American in a harrowing flight for freedom along the Underground Railroad."
