Kwame Alexander has written seventeen books, owned several publishing companies, written for television (TLC's Hip Hop Harry), recorded a CD, performed around the world, produced jazz and book festivals, hosted a weekly radio show, worked for the U.S. government, and taught in a high school.

Recently Kwame was a visiting writer in Brazil and Africa. He resides in the Washington, DC, area, where he is the founding director of Book-in-a-Day (BID), a program that teaches and empowers teenagers to write and publish their own books.

The idea for He Said, She Said came during a writing workshop he conducted with thirty smart, funny, feisty, insecure, and ambitious young people in Charleston, South Carolina - which, by the way, is his favorite place on earth (behind Bahia, Accra, and Tuscany, of course).

Melissa Sweet has illustrated nearly 100 books for children, including Some Writer! The Story of E. B.White, which she also wrote, and The Right Word: Roget and His Thesaurus, which was awarded a Caldecott Honor.

She is also the illustrator of Firefly July: A Year of Very Short Poems. Melissa Sweet lives in Portland, USA.
