Rose in Chains (original) Julie Soto

The war is over, the dark forces have won, and the hero who was supposed to save them is dead. 

Captured as her castle is overrun by the enemy, the world as Briony Rosewood knows it is changed forever. Evil has won, and her people face imminent servitude, imprisonment, or death. 

Stripped of her Magic and her freedom, Briony and the other survivors are quickly sold off to the highest bidders in an auction—and as Evermore's princess, she fetches the highest price. After a fierce bidding war, she’s sold to none other than Toven Hearst, scion of a family known for their cruelty.
