Probably the best example I can think of is Diane Duane reworking her Wizards series to make it modern-day, but there are others, including owners of a literary estate altering books left to them to make them compatible with current standards.
What do you think? Does it matter if it’s the original author or an inheritor?
Every time there was a new edition of a “Saint” book Leslie Charteris used to make changes to modernise it - change the cars, fashion, etc.
Acceptable but as a reader I’d rather he’d spent the time writing a new one instead.
