She co-authored her first book, "Smelling The Breezes", with her husband Ralph Izzard in 1959, and was republished as "A Walk in the Mountains" in the United States the following year. The book Izzard wrote was about the two-month camping trek she and her family took through the High Lebanon mountains by donkey in 1957. Izzard's second book, "A Private Life", followed in 1963. She detailed in the book her memories of the first seven years of her marriage to Ralph Izzard reporting on the Partition of India, and bringing up her family amongst the Egyptian revolution of 1952 and the conclusion of British rule in Cyprus in 1960. In 1969, she authored "A Life of Dame Helen Gwynne Vaughan" on a commission from her publishers. Ten years later, Izzard wrote, "The Gulf: Arabian Western Approaches", which was a first-hand account of the rise of the nation-states Bahrain, Kuwait and the Emirates set against Saudi Arabia's restrictive Wahabism as well as Iraqi and Iranian power when Anglo oil companies lost their grip on the region.
