Gwen Reese has just learned that her mother is Blodeuwedd, a Welsh goddess who was cursed several thousand years ago after she plotted with her lover to kill her husband. It’s bad enough being a teenager and dealing with all that comes with that, but just when she begins to learn a few truths about her past and the parents who abandoned her when she was only a toddler, she now has to deal with the fact that she’s a demigod with a whole host of gifts she has no idea how to control.
It is new territory that Gwen must learn to navigate, but she’s not alone. Cei, Gwen’s foster brother, is a servant to the gods who was granted immortality when he chose the life of servitude. It is his role to protect Gwen and to help her to find a way to break the curse that has kept the sons of Don, practitioners of light magic, trapped in the Welsh Underworld, Annwn, for thousands of years.
Along with Cei, Gwen gets help from Rhein, another immortal servant who knows enough about the magic Gwen has inherited from her mother to help her figure out how to control it. And then there’s Morgan, another demigod who, like Gwen, had not only learned he’s a demigod, but must deal with the added knowledge that his mother cheated on his father and that the man he has called father all his life is not his biological father.
On top of all that Gwen, Cei, Rhein, and Morgan have to deal with, there is also a crazed goddess out there who wants to stop Gwen from breaking the curse and freeing the sons of Don. Branwen has grown more powerful as the sons of Don have been locked up and she’s not going to give up that new power without a fight. And the cherry on the cake? There might be a traitor in their midst.
