Query: My favorite childhood book

I read this book when I was 10 years old (I am now 40) and I never forgot it. When my niece turned 11 I searched and searched for this book to give it to her on her birthday. I finally found this "like new" copy on Amazon. I guess this book is out of print now because I could not find any new copies. The story of Sibby is one that every girl should read. It is a beautifully written story of a young girl's loyalty, strength and courage to do the right thing. This gem belongs on the shelf next to The Chronicles of Narnia.
