Lian (An-Li) Cho grew up in New Zealand, far away from her eight aunts in Taiwan, where she was born. Now she lives in Brooklyn and is the illustrator of quite a few absurd books for kids, including The Oboe Goes Boom Boom Boom by Colleen AF Venable and It Began with Lemonade by Gideon Sterer. She hopes to one day learn how to quilt, but in the meantime, she enjoys baking copious amounts of banana bread, watching terrible movies, and creating small felt creatures.
