A haunting and beautiful retelling of a classic myth, The Daughters of Ys is the story of two sisters and what happens to them after their mother's sudden death. When their father responds to his grief in socially frowned upon ways, the daughters diverge. One heads away from the castle and into nature, while the other dives into her new found power and the elusive mystery of Ys. 

If you don't know the myth, I suggest reading this one without knowing anything more. That will make it much more surprising and fun.
