Genre: Historical Fiction
A brutal murder. A castle under siege. A family torn apart by the Scottish Reformation.
Scotland, 1546. When Protestant rebels seize St Andrews Castle and assassinate Cardinal Beaton, the most powerful man in Scotland, young Will Seton joins the occupiers, convinced he is fighting for a better future.
His sister Bethia fears he has made a terrible mistake.
As the castle comes under siege and Scotland edges towards religious war, Bethia watches her family become caught between powerful forces beyond their control. While Will endures hunger, fear and mounting despair behind the castle walls, Bethia must decide how far she is willing to go to save the brother she loves—even if it means risking everything.
But this is more than a conflict between brother and sister. As Henry VIII pressures Scotland to surrender its independence and secure the marriage of the infant Mary Queen of Scots to his son, the future of an entire nation hangs in the balance.
Based on the dramatic true events of the Siege of St Andrews Castle, The Castilians is a gripping tale of faith, loyalty, courage and survival during one of the most turbulent periods in Scottish history.
The Castilians is Book One of The Seton Chronicles, an award-winning and best-selling historical fiction series spanning Scotland, Venice, France and Constantinople during the turbulent years of the Reformation
The Castilians opens during one of the most dramatic episodes of the Scottish Reformation—the siege of St Andrews Castle. What first drew you to this fascinating period of Scottish history?
I grew up on a farm near St Andrews and went to school in the town, but I didn’t really learn much about its history, nor had I ever been in the ruins of the castle and cathedral until I was twelve, when our history teacher took us.
I was fascinated by the castle and especially the siege tunnel – the best preserved one of the period (1546) in Europe.
At school we were taught that the Protestants were the heroes of the siege. It all seemed quite straightforward. In the early days of the Reformation when Scotland was still Catholic, the reformer George Wishart was burned at the stake outside the castle walls on Cardinal Beaton’s orders, Beaton was assassinated in revenge, and the Protestant defenders heroically held out during the siege.
It was only years later, while researching the novel, that I realised the reality was far more complicated. The Protestant leaders occupying the castle weren’t simply fighting for religious freedom. Many were also receiving support from Henry VIII, who was trying to force Scotland into accepting the marriage of the infant Mary, Queen of Scots, to his son Edward. Religion, politics and international power were completely intertwined. That complexity fascinated me, and I wanted to tell the story through the eyes of ordinary people living through those events.
The story follows siblings Will and Bethia Seton, whose lives are shaped by the religious and political turmoil around them. What inspired these characters, and why did you choose to tell the story through their perspectives?
History usually remembers the famous names, but I wanted to explore what these events meant for ordinary families. Will and Bethia gave me two different perspectives on the same conflict.
Will is young, idealistic and convinced he is helping to build a better Scotland. Bethia is more cautious. She loves her brother but fears the choices he is making will have consequences for the whole family.
Using siblings allowed me to show that the Reformation wasn’t simply a struggle between opposing sides. It divided families, friendships and communities, forcing people to make impossible choices.
Will believes he is fighting for a better future, while Bethia fears he has made a dangerous mistake. How important was it for you to explore different viewpoints on the Reformation and the conflicts it created within families?
That was central to the novel. It’s easy to judge the past with the benefit of hindsight, but people living through the Reformation didn’t know how events would turn out. Catholics and Protestants alike genuinely believed they were defending the truth.
Throughout the series I’ve tried to avoid presenting either side as wholly right or wrong. Instead, I wanted readers to understand why decent people reached very different conclusions and how those differences could divide even the closest families.
The novel is based on real historical events, including the assassination of Cardinal Beaton and the subsequent siege. How did you balance historical fact with the demands of storytelling?
The history always comes first. The major events happen when they happened, and the historical figures remain as true to the evidence as possible.
The fictional characters are then woven into those events. Rather than changing history to fit the story, I let the story grow naturally from history. I spent time researching contemporary accounts, in the National Library of Scotland, visiting locations and reading work by academics studying the period. Often the real events were more dramatic than anything I could have invented.
Faith, loyalty, and survival are central themes throughout the novel. Which of these themes resonated most strongly with you while writing The Castilians?
Loyalty. My characters are constantly forced to choose between loyalty to family, faith, friends and country, and those loyalties don’t always point in the same direction.
Although the story is set nearly five hundred years ago, those emotional dilemmas are timeless. Most of us have experienced times when there isn’t an obvious right answer, and I think that’s what readers connect with most strongly.
Scotland in 1546 was caught between internal religious upheaval and external pressure from Henry VIII. What aspects of this turbulent political landscape did you most want readers to understand?
That religion was only part of the story. Scotland stood between powerful neighbours with competing interests. Henry VIII wanted to dominate Scotland through the proposed marriage of his son Edward to the infant Mary, Queen of Scots, while France remained Scotland’s long-standing ally and Mary of Guise, Mary Queen of Scots mother is obviously representing French and especially the Guise Family, interests
Religion, politics and international diplomacy became impossible to separate. Understanding that wider picture helps explain why people made the decisions they did.
Readers often praise the vivid historical detail in your novels. What research discoveries most surprised or fascinated you while writing The Castilians?
I was struck by how connected Scotland already was to Europe. Merchants, scholars, diplomats and soldiers travelled constantly between countries, carrying ideas as well as goods.
I also loved uncovering the details of everyday life—what people ate during a siege, how they travelled, what happened when disease broke out, and how ordinary families survived extraordinary times. Those details help make the past feel real.
The Seton Chronicles eventually takes readers beyond Scotland to places including Venice, France, and Constantinople. What inspired you to expand the series across such a wide geographical and historical canvas?
When I finished The Castilians, I realised Scotland’s story didn’t end at its borders. Scots travelled across Europe as merchants, soldiers, scholars and religious refugees, and following the Seton family naturally led me to Antwerp, Venice, France and Constantinople.
One of the most fascinating discoveries was how a person’s safety depended on both their faith and where they happened to be. Geneva became a refuge for Protestants but was dangerous for Catholics. Venice, meanwhile, was no place for Protestants, yet Jews could live there more openly than in much of Europe. In fact, the word ghetto originated in Venice, where the Jewish community lived in a designated district.
Those constantly shifting boundaries of tolerance and persecution gave me the opportunity to explore the wider story of the Reformation across Europe, rather than through the experience of living one country alone.
As the opening novel in The Seton Chronicles, The Castilians lays the groundwork for a saga that spans multiple countries and decades. When you began writing the book, how much of the wider series had you already planned?
The honest answer is—not at all.
I thought I was writing a standalone novel. But when readers reached the end, the question they kept asking was, “What happens next?” I realised I wasn’t ready to leave Will and Bethia behind either.
One book grew into five, following the Seton family across Europe through more than forty years of religious conflict, exile and survival. I’m very glad I listened to my readers.
For readers discovering The Seton Chronicles for the first time, what do you hope they take away from The Castilians and the journey that lies ahead for the Seton family?
Above all, I hope readers become immersed in another world and come to care about the Seton family as much as I do.
The series follows one family through some of the most turbulent decades in European history, but at its heart it’s about ordinary people trying to hold on to those they love while the world around them changes beyond recognition.
If readers finish The Castilians wanting to know what happens next to Will, Bethia and the generations that follow, then I’ve done my job.
My thanks to V.E.H. Masters for this fascinating interview and for sharing the inspiration and research behind The Castilians. It has been a pleasure learning more about the real history that shaped The Seton Chronicles and the ordinary people whose lives were transformed by extraordinary events. I wish V.E.H. every success with The Castilians and the rest of this remarkable series, and I hope readers will enjoy following the Seton family on their unforgettable journey through one of the most turbulent periods in European history.
