I love her writing, and I think she should write more. But I don't think she's going to.
Didn't she say that she didn't really have anymore ideas? It seemed to me that after the 5th book, she kinda started forcing her books. She's still an amazing writer, I just don't think she'll write anymore. Atleast not for these series
Plus I kinda like being able to write fanfiction about the next generation of kids.
Just my random thoughts.
