Clackety clack clack clack ... Can you hear the rhythm of the train? Langston Hughes did.

On that ride, he was inspired to write his first famous poem, "The Negro Speaks of Rivers." This picture book tells the story of Langston Hughes's rise to accomplishing his dream of being a writer. With bold, striking illustrations by Leonard Jenkins, here is a book for any young person with a dream.
