The lead character in the novel 'Madeleine's Quest' by Julien Evans is an ex-ATA female pilot who is now a Professor of Chemistry at Oxford University. She still flies light aircraft and during the narrative she is reunited with a Spitfire. Her half-brother (an ex-Lancaster pilot) is now a B707 Captain in BOAC. The story, which follows the twists and turns of the lives of both siblings, is set in 1967-8.
In 1971 I did my FI course with Joan Hughes - a remarkable lady. Modest too - I didn't know of her ATA background until somebody told me later. She flew the Santos-Dumont Demoiselle replica in 'Those Magnificent Men' (the only pilot light enough) and WW1 types in 'The Blue Max'. In the White Waltham restaurant hangs the photo below of tiny Joan dwarfed by the Stirling bomber she's standing beside, which she probably flew.
