From
#1 New York Times bestselling author P. C. Cast—a sexy and
magical epic of Celtic legend, perfect for romantasy fans who love Sue Lynn Tan
and Thea Guanzon.
Step into
the mystical world of the Isle of Skye in 200 BCE, where legends come to life
and the Queen of Shadow holds court. But Scáthach is no ordinary queen.
Daughter of the Underworld goddess Bēfionn, golden-haired Scáthach is gifted
with the Sight, able to glimpse all the possibilities of the future and pass
between the world of men and the world of gods.
Scáthach dedicates her life to training the fiercest warriors from across the
land in her fortress at Lethra. But then a newcomer arrives in Lethra and
upends everything about Scáthach's existence. He is Cuchulainn, the hero of
Ulster, son of the Irish God Lugh. Known for his strength and bouts of
berserker rage, Cuchulainn wants Scáthach to help him hone his skills and find
redemption for his violent past. The Queen of Shadow reluctantly agrees to take
him in, ignoring their growing attraction, and what it might mean for her
destiny.
Meanwhile, Scáthach's jealous half-sister Aife threatens Scáthach’s claim to
the kingdom she loves and challenges Scáthach for Cuchulainn’s loyalty. Caught
in a snare of duty and desire as she navigates the perils of leadership,
Scáthach discovers that her destiny may lie in the Underworld, where she can
forge a future for herself and Cuchulainn by tricking death itself....
My Review: P. C. has blown me away YET AGAIN. How does she always do this?!
Then you have Cuchulainn who really deep down is a big softie. He first started off on a rough note after breaking Scathach's door. But Scathach accepts his request to be a student in the end. He excels at everything but he doesn't show off. He doesn't boast. He even helps and encourages the other students. Scathach really likes that bout him among other things.
As the story goes on, there is so much that is packed into this book and I love every moment of it. WELL - actually not one scene. There is a scene about a horse and well don't read it is all I can say. As an animal person, this was hard to read so go ahead and skip that part.
Scathach also has the best daughter and guard leader who is really more like her best friend. Those are some of the best side characters and I loved them.
Scathach's sister is a no go. Don't like her nor what she did. That may also be a rough scene for folks who may be more sensitive about SA, so just keep that in mind.
But overall... This book was simply amazing.
I've been a fan of P. C. for ages now and will always boast about her books. She's an absolute favorite of mine and haven't come across one book I haven't loved yet. This was no exception, in fact it made it to the top of the list.
