A forbidden love story set against the brutality and spectacle of medieval war. England, 1333. As Edward III wages war against Scotland, nineteen-year-old knight Harry de Lyon is desperate to prove himself. When he is chosen for a covert mission led by one of the realm's most powerful men, it feels like his moment has finally come. What follows is something far darker. At a ruined Scottish keep, Harry helps capture a wild, half-starved boy, a prisoner no one can explain. Given the boy as his squire and ordered to break him, Harry expects resistance. Instead, he begins to uncover something far more unsettling: the boy is educated, multilingual, and hiding a past that does not fit the story he has been told.

As the two are drawn closer together, their connection deepens into something dangerous, something neither of them can afford. At court, Harry rises through the ranks, winning favour and glory, but beneath the pageantry lie secrets that could destroy them both. The Scottish Bo y is a story of power, identity and desire in a world where loyalty is everything and love is a risk that can cost you your life.
