Before She Was Harriet, is a beautiful, lyrically written book by Lesa Cline-Ransome, illustrated by James Ransome. Though there are many books about Harriet Tubman, this one is special because it tells her story in reverse order. By starting from the end, and showing you what amazing things she was at the end of her life (even more than you thought you knew), by the time you arrive at the beginning of her life , there is so much more awe in her humble beginnings and what she was able to accomplish.
As a non-fiction writer, this is a great mentor text for a reverse chronological order style of writing.
