“The Substitute Bride” is a fantasy romance novel by Olga Herr in the genres of love fantasy and adventure fantasy. In the Land of Mists, savage customs rule: only an innocent girl will survive through their marriage rite. But my sister has long given her heart—and her first night—to her beloved. However, princesses don’t choose husbands. A union with the Land of Mists is necessary for our kingdom. The problem is that the wedding with their ruler will kill my sister. So she begs me for help and asks me to take her place. I’m innocent—and that means I’ll survive. But to hand myself over to a stranger fiancé at the wedding altar… no way, and never! And what if it’s for the sake of saving my only sister?
