Step back into a time when the Iberian Peninsula was torn by constant warfare. Centuries of famous battles and heroic deeds have filled taverns and squares with stories, but there’s one tale that’s been shrouded in silence—perhaps because no one dared to tell it. This is the story of Diego, a young knight whose life is tied to one of history's greatest heroes.

Diego isn’t just any young man; he’s the son of Rodrigo Díaz de Vivar, the legendary Cid. Raised under the strict guidance of his father, Diego is trained to be his finest captain—a goal he pursues relentlessly, even as his once-strong filial devotion fades. With each passing year, Diego’s loyalty to his father is tested, especially under the watchful eyes of his mother, Jimena, who sees the bitterness transforming the Cid into a cruel figure. As he grows, Diego, ever the loyal vassal, must confront a painful truth about the man he has idolized his entire life.

Through the powerful and epic storytelling of Francisco Narla, The Loyal Vassal transports readers to the legendary Spanish medieval era, weaving a vivid tapestry of characters that are integral to our shared heritage. Themes of honor, vengeance, redemption, and love intertwine in this dazzling historical novel, which is as compelling as it is timeless.
