Mail-Order Lady (Lords of the Rockies, #4)

Five sons of an English duke, all raised in the Rocky Mountains…
She agreed to a safe, sensible marriage. He agreed because she already holds his heart.

Clara McKinney came west as a mail-order bride—only to watch her sister marry the intended groom instead. Now recovered from an illness that nearly killed her, she's stranded at the Balfour ranch. Worse, her mother is demanding her return to face an arranged marriage that feels like a nightmare. When the quiet, bookish brother offers a marriage of convenience, Clara accepts with relief. No messy emotions or risk of rejection. Just safety.

Robert Balfour has one goal—win Clara’s heart. She now shares his name, but he must convince her that his devotion runs deeper than courtesy.

Then a stranger appears at the ranch with a shocking claim—he's the rightful Balfour heir. Suddenly, Robert’s focus on earning his wife’s love faces a test he never saw coming. With enemies lurking and family loyalties tested, this marriage of convenience is about to become the most dangerous arrangement of all.

From a USA Today bestselling author comes a royal family saga featuring a marriage of convenience, unrequited love, and a family mystery that spans continents…all set in the rugged Montana Territory.
