Swan Sister: Fairy Tales Retold by Ellen Datlow (Editor), Terri Windling (Editor) is on sale for $2.99 in ebook format, the lowest price it has reached to my knowledge. It's usually in the $7.99 price range.
It's a great book--I own it in hardcover and ebook and it has some lovely stories by some favorite authors. But I will admit, it has a special place in my heart for an additional reason:
Just as fairy-tale magic can transform a loved one into a swan, the contributors to this book have transformed traditional fairy tales and legends into stories that are completely original, yet still tantalizingly familiar
In the follow-up to A Wolf at the Door, thirteen renowned authors come together with a selection of new and surprising adaptations of the fairy tales we think we know so well. These fresh takes on classic tales will show you sides of each story you never dreamed of.
