Trixie Belden and the Bob Whites of the Glen were my first best friends before I finally worked up the courage to try to make friends in the real world. A fellow 365 picture reminded me to smile about her one more time http://365project.org/jld29/365/2014-07-09@jld29
I was a Laura Ingalls Wilder girl. But I think series books like these are so great. Looks like your treasured friends have a special spot on the shelf!
