One summer Jean learned that the wolves were friendly, lived in a well-run society and com

municated with each other in wolf talk - sound, sight, posture, scent and coloration. Excited to learn more, she took Luke and went to the Naval Arctic Research Laboratory in Barrow, Alaska, where scientists were studying this remarkable animal. She even talked to the wolves in their own language. With that Julie of the Wolves was born. A little girl walking on the vast lonesome tundra outside Barrow, and a magnificent alpha male wolf, leader of a pack in Denali National Park were the inspiration for the characters in the book. Years later, after many requests from her readers, she wrote the sequels, Julie and Julie's Wolf Pack.
