Basically, Kurt was a servant to Sebastian, who was either a prince or a duke or something. Sebastian is arranged to marry another prince who he never met before, and Kurt has to travel with him to the new kingdom, (Sebastian is a jerk to Kurt, Kurt hates him etc.) on the way, they are attacked by bandits or something, and right as Kurt is about to get raped, Blaine, the leader of another clan of bandits, saves the day. They end up being "kidnapped" by Blaine's clan, which basically entail Kurt being treated like royalty, while Sebastian is treated like a prisoner. Blaine and Kurt slowly start a relationship, (Blaine is experienced, Kurt isn't) and that's about all I remember. I also remember that Lauren Zizes was a madam and Jeremiah was a prostitute that I think Blaine used to have a bit of a thing with, but they were only in the story briefly.
Let me know if you find it, thanks so much!!!
