Katrina Goldsaito's favorite sound is the sound of bare feet on tatami mats. In Tokyo, she worked as an on-camera TV journalist and producer for NHK-World, and has written for National Geographic, TheChristian Science Monitor, NPR, and The Japan Times. She lives near Golden Gate Park with her husband and son, and spends her days eating avocados and working on her first YA novel.

Julia Kuo's favorite sound is kuk-kuk-kuk (the sound an angry squirrel makes). She is the illustrator of Go, Little Green Truck and has created illustrations for American Greetings, the Cleveland Public Library, The New York Times, and Capitol Records, among many others. She works from Chicago for most of the year, and from Taipei over the winter.
