Birthday coming up for friend in her 70s. She is wealthy, has everything she needs, is on a massive health kick so not drinking or eating chocolates etc. I will buy her her favourite flowers and a book. Beyond that I am stumped. Anything generic like a candle seems a bit insulting. Normally I would take her out for dinner but that can’t happen this year. Help! In particular any book suggestions welcome... she is more keen on nonfiction.
