Loved those books when I was a kid smile I think I still have the five I got autographed by Ann M Martin somewhere, but I'm not sure where. The first one I read was the pet-sitter one with Jessi, I think, and I was very proud of myself for reading a book with such 'little' print ;p

Grant me the serenity to accept the things I cannot change,
The courage to change the things I can,
And the wisdom to know the difference.
