The Judge's Bride (Montana Brides of Solomon's Valley #1)
Patricia PacJac Carroll

Judge Solomon Taggart groaned at having to referee a dispute between the two feuding families. That even their children were at each other made him doubt the wisdom of sending that letter to the widow in Minnesota. She had children. She didn't say how many, and he hadn't asked. He grabbed his rifle and swung up in the saddle, praying there'd be no bloodshed. And then he prayed he'd been wise to send that letter.
