Marianne Hering has written for children since 1987, when she was on the staff of Focus on the Family and launched both Clubhouse and Clubhouse Jr. magazines. She has written more than 40 children's books, including the successful Imagination Station series. When she isn't writing, she's adventuring in the Colorado Rockies with her family and dog, Sam.

Marshal Younger has written about 200 episodes for the Adventures in Odyssey radio program. He has also written four Adventures in Odyssey Kidsboro novels and several books in the Imagination Station series. Marshal lives in Colorado and gets most of his ideas from stories about his wife, four children, and five grandchildren (much to their chagrin).
