Meet Karlin Gray As a little girl, Karlin Gray loved gymnastics but she wasn't feisty, fearless, or focused like Nadia Comaneci. Karlin had no problem sitting still . . . daydreaming and, eventually, writing. After working several years in publishing, she sat down and wrote her first picture book, Nadia: The Girl Who Couldn't Sit Still. Karlin lives in Connecticut with her husband, son, and a very bouncy dog.
