I think that’s part of what made the series so popular though. She did a great job at letting the characters in the books grow up alongside the readers. Someone who read the first book when they were 7 could enjoy the last book when they were 14.

I haven’t re-read the books since I finished them sometime around that age, so I won’t comment on the world-building or writing outside of recalling that I was completely absorbed and fascinated when I read them.
