Barbara Dacosta

Barbara DaCosta, as a child, was a precocious nighttime ninja, constantly climbing out of the crib in search of cookies and other interesting things. She has since cut back on the climbing and the cookies, but still enjoys finding the interesting things in life to write about. Nighttime Ninja is her first children's picture book. She makes her home in Minneapolis, Minnesota.

He has also written and illustrated The House Baba Built, which recounts his childhood in Shanghai. Born in China, Ed moved to the United States as a young man and pursued his love of art. Nighttime Ninja is the type of picture book Ed would have loved as a young boy. He currently lives in New York.
