I was going to suggest anything by Mary Potts, but since that has already happened... *sigh*
How about Sue's Proof Series? You'll find the various titles
here Or how about
Lois\' Cooking Diary by Supermom?
Or... if your daughter is a little into this whole Batman thing:
A Sister Would Know by LaraMoon. Of course, there are sequels...
Or
Robitussin by JenD? Just my two cents worth of stories.
EDIT: I totally forgot Ann's
The The Adventures of Clara Ellen Lane . Unfortunately, it's not on the archive, but that doesn't matter much, does it? *g*
