Query: Easily my favorite book!

This is definately my favorite book. The imaginative story of Meryl and Addie--best friends gives you fears and surprises. You never know what to expect. Especially the ending. This book is worth reading just to find out what happens in the end. It made me sad and wish that it weren't the ending. It taught me fairy tales dont' ALWAYS have the happiest possible ending. Read it and find out for yourselF!!
