Disclaimer! This was an ARC from Netgalley (but I have also paid to buy the book myself, after reading it). My opinions are my own.
Every one hundred years, the king of the Sheltered Lands has to send one heir to serve as consort to the ancient dragon god who acts as its protector and guardian. The previous consort went mad with fear not long after bonding with the Dragon, and Ash, the Dragon, worries that history will repeat itself. Ash has lived for over three thousand years, and even with successful unions, his consorts, being mere mortals, grow old and die. Yet the tradition must continue or the protective spells on the land can’t be renewed.
The consort is obviously supposed to be of royal blood, but this time, the king has sent an impostor. Sachielle and her handmaiden Zenya were orphans, adopted, and trained to be the perfect weapons. Sachi has been trained to seduce and beguile, Zenya to be a ruthless and highly efficient assassin. Both young women have faced a very harsh and torturous upbringing, with the safety of the other used to keep them under control during training. Their secret mission is to murder the Dragon when he is most vulnerable, and they have only five weeks to complete their task. If they fail, the king’s high priest has placed a curse on Sachi. She will die painfully and her soul will be consumed. Zenya has never known love in her life, except from Sachi, and will do anything and everything to keep her safe – even something as impossible as murdering a living god.
Of course, Ash turns out to be nothing like what the young women have been led to expect, nor are the other living gods of the pantheon, all of whom do their best to make the young women feel welcome. The Dragon is not the ruthless tyrant that they feared, he is beloved of his followers and treats both of them with kindness and solicitude. Nor is he even vaguely threatened when he discovers that his bonded bride and her handmaiden are lovers – he just becomes determined to seduce both of them. The more time they spend together, the more willing Sachi is to just give up on the assassination plot, but Zenya isn’t going to let her beloved be consumed by the curse, no matter how charming and hot the Dragon is.
