Set in a medieval world, one girl dreams of being an inventor creating things. While her brother wishes to become a witch of sorts, herbal medicine and magic such as spell casting summoning. Only female virgins can use magic in this world. Both the twins wish to be the other, both wanting the other's destiny. Can they rewrite what is set in stone what the elders say fate can not be changed, but what if their fate is to change the way world works, make everyone equal, males and females doing the same jobs, following their dreams. The dreams that ones heart tells them, to chase them down.
All Willow Walters ever dreamt of was a bit of action in her life. She'd spent endless nights with her little sister, fantasizing about what they would do if they were brought into a parallel world full of mysteries and magic.
But when the day of the impossible does come, Willow becomes unsure if that was what she had really wanted all along.
If castles and magic really were the same as in the books.
