My sister Pip was a great reader of books, from childhood onwards. We had an aunt, Jean, who gave us lots of books (but not this one). Pip read The Stone Cage in childhood, loved it and, as an adult, was on the lookout for a copy. She visited secondhand bookshops regularly (this was before the days of Ebay and Amazon). One day she found what she'd been searching for - a copy of The Stone Cage. She opened it up and read on the flyleaf 'To Pip, with love from Jean'. She didn't buy it as she said it felt too weird.
