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?
If it’s obviously marked as a different edition then that’s fine. My grandparents rewrote my great-grandfather’s entire book series to make it more modern since it’s mainly for kids and teens.
