Ginnie Lo and her sister Beth are the creators of Mahjong All Day Long, which won the Marion Vannett Ridgway Award for an outstanding picture book debut. Like their first book, Auntie Yang's Great Soybean Picnic is inspired by the sisters' memories of growing up Chinese American in the Midwest.

Ginnie Lo is a retired computer science professor who taught at the University of Oregon for many years. She enjoys hiking, international folk dancing, and traveling--especially taking family trips to China. The mother of two grown children, she lives with her husband in Eugene, Oregon.
