Rebel Bride by Ava Sinclair

Three dragon lords saved me. Now they plan to make me their own.When the ShadowFell dragon destroyed my village, I alone survived the slaughter. A Drakoryan rescued me from where I clung to life in the bottom of a well. From the moment Lord Turin saw me, he was determined that he and his brothers would take me for a mate.
To do so would mean breaking the rules. Drakoryans bring mates to the empire only by special permission of the witches. But as war begins with the ShadowFell, everything has changed. The villagers from across the mountains have been brought here for protection. The time of sacrifice is at end, and the Lords of Za’vol are being allowed to take me as a specially designated mate – a War Bride.
I should be grateful that the Drakoryans saved me. But I know what they are. They are drake shifters. How can I accept their dragon side, when it was a dragon that robbed me of everyone and everything I held dear?
The Lords of Za’Vol are determined to mate with me, to form a lasting bond despite my fear of them. But I want something in return. I want to be brave, so brave that no man or beast can ever hurt me again. If the Drakoryans are to claim me, they must train me to fight.

– For centuries, the Drakoryan lords have taken sacrificial maidens. As a village widow, I thought myself safe from their attentions. I was wrong.
I am Thera the Healer, and I blame the Drakoryans for the death of my husband and father. They were killed before our dragon lord rulers resettled us in the Drakoryan Valley ahead of war with the ShadowFell.
Now they seek to recruit village men into their army to fight the enemy. But I seek to convince my people that the enemy is not some black dragon we have never seen, but the one who keeps us.
Now the Drakoryans are accusing me of sedition, and seek to neutralize my influence in a manner I will not accept. They seek to wed me to five Drakoryan lords tasked with keeping order in my village.
They won’t get what they want without a fight.
