The Heart Behind the Gears: The Final Battle at Old Town Hall

By Tricia Goyer (with Nathan Goyer)

Writing has always been a way for me to explore the quiet corners of history. This was true for my newest novel Twist of Time. Through this book, I step into a world that is both familiar and utterly mysterious. The book is set in Prague in 1945. I first visited Prague as a wannabe writer in 2001. Then, in 2008, I went back with my family and our church group. I’ve been there numerous times, most recently in 2024 when I was working on this book. I was able to go underground underneath the clock to see where the resistance fighters hid.

Collaborating with my son, Nathan, on the conclusion of The Clockwork Chronicles has been a highlight of my career. We wanted to take the grit of May 1945 Prague and weave it together with the ancient, ticking secrets of the Orloj—the city’s famous astronomical clock.

In this final chapter, the stakes are anchored in the very real, devastating history of the Prague Uprising. On May 8, 1945, the Old Town Hall became a focal point of fierce resistance. As the German forces retreated, they directed heavy fire toward the building, leading to a catastrophic fire that destroyed the municipal archives and heavily damaged the clock. We imagined our characters, Katerina and Josef, caught in this chaos, where the smoke of history meets the supernatural shadows hinted at throughout this series.

While the town hall burned, the Czech resistance fought with everything they had. In our story, this physical battle is a mirror to a much larger, spiritual confrontation. We often think of history as a series of dates, but I believe it is actually a tapestry of souls choosing light over darkness.

Researching the legends of Prague Castle and the hidden depths beneath the city inspired us to ask: What would you do if you realized the war you were fighting was only a shadow of a much larger battle?

We hope this story of Josef, Theodora, Dante, and Katerina reminds you that even when time seems to be running out, hope is never late. I am so grateful to have you join us for this tour. Whether you have been with us since the first gear turned or you are just now discovering this world, we hope Twist of Time keeps you breathless until the very end.
