Bio: Melanie Hope Greenberg has illustrated 16 children’s picture books; six of them she wrote. Greenberg's blog, Mermaids On Parade, named for her latest book, was selected "100 Best Book Blogs for Kids Tweens and Teens". In the Fall 2010, her art is part of "Drawn in Brooklyn", a group exhibition of picture book artists, curated by John Bemelmans Marciano, at the Brooklyn Central Library-Grand Army Plaza. Greenberg will donate her original picture book art for the Disaster Relief Fund raffle at the Texas Library Association's annual conference 2011.
