Aviation adventures are Shirlee Smith Matheson’s specialty. In Maverick in the Sky the author paints a fascinating portrait of WW1 flying ace Freddie McCall, one of the most successful fighter pilots of World War I. McCall’s bold spirit might well have been inherited from his clan motto Dulce Periculum – Danger is Sweet. His amazing wartime accomplishments, his extraordinary flying skills, his fiercely independent barnstorming character and his self-reliant entrepreneurial spirit make him one of Canada’s most spectacular mavericks.
