Sold To A Stepbrother

In a Middle Ages alternate universe, where same-sex royal matches and male pregnancy are commonplace, Sir Christian of the small principality of Lannim - heir to his father Prince Henry - is in a rare taking. And wouldn't anyone be, given the news? Prince Henry has made a match for him - practically selling him off as a child-bearing potential spouse to the neighbouring royal family of Tallot. And not only that - but Prince Henry was formerly married to the Queen of Tallot, Griselda, in a fiery political union that ended in divorce, scandal and near-war. And now, to make the peace, Christian is about to be married off to... his former step-brother, Prince Daniel.

His step-brother, old friend, former tormentor, companion, and co-conspirator in all kinds of mischief... now to be his husband, eh? And not only that, but Daniel hasn't even troubled to remain in contact, in the years since they last saw each other.

What kind of sparks are liable to fly, should Daniel turn up on the palace doorstep, unannounced...?
