I read this back in 1999 from the school library. I returned it, grew up, forgot its title, but always remembered reading a story of five paper dolls going on an amazing adventure. Finally, this year, I did some sleuthing and re-found this beautiful book that I haven't seen in two decades.
I see now why this story in particular stayed with me and haunted me for so many years. Particularly Elodie, the crying sister, always hovered somewhere in my subconscious. It's such a fun, beautiful, sweet, profound story. I guess, like Sally, I knew I would never forget the five sisters. And now, I finally have them back!
