With This Ring by RS McKenzie

Carter Whitlock
Family means everything to me. I’ll do everything I can to keep them safe. That includes marrying my enemy.
Kaison St. Clair has been a thorn in my side for years. When we see each other, we either trade insults or blows. I hate everything about him. If it were up to me, I’d stay far away from him and the entire St. Clair family.
But someone is after both our families. The only way to keep everyone alive is an arranged marriage with my enemy to combine the might of the St. Clair’s and the Whitlock’s.
Life with Kai is supposed to be about winning the war we found ourselves in, not love and emotions. But somewhere down the line, he gets under my skin.
And I’ll do whatever it takes to make him mine in more than name.
