I'm always slightly worried about buying her an older book as she always seems to have read them, plus she loves a hardback, so if anyone can recommend something newly published along these lines:
-books about the aristocracy or diplomats; she loved the Lady Glenconner book
-romantic novels with NO sex and a very happy ending, she liked The Grand Sophy by Georgette Heyer for example
-detective novels of the gentler sort, i.e. no serial killers or gore
-non-fiction books with nice photos/pics about gardening or natural history
Thanking you!
