When she was in grade five and six, she and several friends had a writing club. "We'd gather with our most recent poems and stories and read them aloud to one another. We always tried to say one thing that was positive, along with a more critical but constructive comment." Also, crazy about horses, she and a good friend, Barb, began writing and "publishing" a magazine about horses and horseback riding. "We sold The Saddle and Bridle Club magazine to our friends for five cents an issue!" Michael Wandelmaier grew up in Ottawa, Ontario, in a family of science geeks with artistic temperaments.
