Two Carriages, One Funeral

Seven days after our divorce, my ex-husband is marrying my sister. Now he and my family have arranged a second wedding for me - with a man I refused. While my sister leaves in a carriage to cheers and blessings, I'm bound, gagged, and forced into mine. Two wedding carriages set out that morning. Only one bride will arrive alive. When they finally hear my silence, will regret come too late?
