Dear Joan comprises a unique series of letters between a young airman, Tony Ross, and Joan Charles, a girl whom he met briefly in England before he was posted to the Mediterranean during the Second World War. Through these letters, the book traces the development of their relationship from friendship to long-lasting love.

With the enthusiasm of youth, Tony and Joan share their dreams of an ideal life in a reconstructed, post-Second World War Britain. Joan's letters reveal the problems of daily life in wartime Britain and give an insight into her voluntary work for the Fire Guard, the land army and the Red Cross, and the bureaucracy she encounters in her job with the Civil Service. Meanwhile, Tony describes the challenges of life in the desert, his increasing responsibilities in the RAF and his experiences in the numerous countries he visits throughout the Middle East.

Dear Joan is a touching account of how Tony's and Joan's love began with a chance wartime encounter and quickly blossomed through letters exchanged throughout the Second World War, across the miles that separated them.
