B-E-S-T Friends — Patricia Reilly Giff

That's what Stacy thinks the new girl Annie is.  And having to be Annie's partner in class is  horrible too. Annie stores her snack in the wrong place,  and she has no front teeth. Her whistling scares  away the birds outdoors. Annie just doesn't do one  thing the way everybody else  does.

It's not easy for Stacy to be friends with someone  who says potatoes are for breakfast. Then she  tries some for herself and discovers it is fun to be  different.
