The entire basis of my story is to have a young teenage girl on the American frontier marry an (obviously attractive) adult man and chronicle the journey of how they eventually come to love each other. The major problem is coming up with a feasible excuse for their marriage in the first place. So far my ideas and their challenges have been: Guy needs a wife to take a particular job (but what sort of job in 1884 would require this?) Girl is raped and parents want to marry her off to save face in case she's pregnant (but what's in it for Prince Charming?) Sadly, those are the only two scenarios I've considered. I've written about 30,000 words in nonchronological snippets that my friends have read and are all crazy to see in finished form, but I just can't seem to get over this massive crevasse in my plot outline. What angle could I use to come at this thing?
