Choi has collaborated with her mother, Sook Nyul Choi, on her many books for children and young adults. A second-generation Korean American and a parent of two, Choi seeks to preserve knowledge and a connectedness to one's heritage by keeping Korean traditions alive in her family. Kathleen Choi was born and raised in New York City and now lives in the Boston area. Sook Nyul Choi is the author of the award-winning Year of Impossible Goodbyes, an autobiographically based novel telling her dramatic escape from North Korea to South Korea in the aftermath of World War II. The first in a trilogy, the two subsequent volumes, Echoes of the White Giraffe and Gathering of Pearls, tell her story of defying odds to eventually win a scholarship and emigrate to the United States. In addition to her novels, she has written three children's books: Halmoni and the Picnic, Yunmi and Halmoni's Trip, and The Best Older Sister. Giving Thanks with Halmoni is her latest collaboration with her daughter, Kathleen. Sook Nyul Choi lives in the suburbs of Washington, D.C.
