Karen's Grandmothers (Baby-Sitters Little Sister #10‪)‬

It's fun to be a Baby-sitters Little Sister! Now available in audio!
When Karen adopts a grandmother from Stoneybrook Manor, she has more grandmas than anyone she knows -- five! Karen thinks that is very special.

But Karen's new grandmother is so different! Grandma B makes Karen listen to old music. And she teaches Karen funny dances, like the foxtrot.

Are five grandmothers too many for Karen?
