1131, The Silk Road.
Gallienus of Constantinople, a scarred soldier who used to work the city gates, enters a new phase of his life when he meets and falls in love with Misahuen of Gyeongju. But prejudice of same-sex relationships dominates Byzantine society, and both the Emperor and the Church denounce such love. Should Misahuen and Gallienus be discovered, the punishment is castration or death. Fearing he'll lose Misahuen, Gallienus decides to go with Misahuen when he leaves the city forever.
A former farmer, Misahuen fled war-torn Korea and journeyed to Constantinople with a merchant caravan. He didn't expect to take such an interest in a wounded soldier at journey's end. But he understands the danger, so he and Gallienus join another caravan as guardsmen and begin a two-thousand-mile trip along the Silk Road. Now all they have to do is persevere to their final destination without the truth of their relationship being discovered and being killed because of it... or by the other dangers along the Road.
