I just finished up the last of a four book series (The Sisterhood of the Dropped Stitches). I knew the series was done, but didn't want to say good-bye. It didn't help that I just got an email from a reader asking if I couldn't find a way to go beyond the four books. How do the rest of you --readers and writers alike -- feel about coming to the end of a series? I know as a reader I often wish series had more books. I get comfortable with characters and don't want to say good-bye.
