Kwame Alexander has written many books and picture books for children, tackling a range of different topics. His newest book, “The Door of No Return,” is the first in a trilogy starting in Ghana in the 1800’s when white colonizers began the slave trade. The book is written as a series of poems, following a young boy, Kofi, who is captured and sold into the slave trade. Kwame Alexander joins us to talk about the 10-year process of working on this book.
