After Marrying the Dead Young Lord, My Husband Returns

When the heir to the ducal mansion dies in battle, my cousin sees her chance—and my fiancé is the prize. On the eve of our wedding, he offers me a choice: become his concubine or walk away. Everyone expects me to accept the humiliation or break down in tears. But when I agree to marry his supposedly dead brother instead, no one anticipates what comes next. The 'deceased' war hero returns—very much alive—and suddenly, I'm the duchess while my scheming cousin remains an unwed marquis's daughter. Let the karma unfold.
