Esther Yu Sumner, the author of "My Nativity ABCs" and "My Nativity 1-2-3s" has been writing stories and poetry since grade school. She decided when she was seven that she wanted to grow up and become a children's book writer. She has also written non-fiction books and other materials working as a writer, editor, and content publisher in roles at Hewlett-Packard, Adobe, and Ancestry. When she's not immersed in a book, dreaming up her own characters, or writing lines in her heads, she enjoys participating in various mountain sports with her husband in Utah.
