Today on the site I’m delighted to welcome Esme Symes-Smith to reveal the cover of the fourth and final book in the MG fantasy Sir Callie series, Sir Callie and the Final Stand, which releases October 14, 2025 from Labyrinth Road/PRH! Here’s the story:
In the conclusion of this bestselling fantasy series a nonbinary knight-in-training, a reluctant crown prince, a fierce young witch, and her resilient twin brother must fight for the heart of their kingdom against tyranny, once and for all.
Helston and its champions have been torn apart by war. Finally reunited after being scattered across the realm fighting personal battles, Callie, Elowen, Edwyn and Willow must prepare to step into the roles they’ve been training for: Champion, Witch, Knight and King.
Even if it feels like their best will never be enough to conquer the infection of hate that has spread across Wyndebrel, even when their numbers seem so small compared to the might of their enemies, they must hold true to their mission: to create a better and safer realm for everyone.
With the aid of Eyrewood, Fairkeep, and the dragons, they are as ready as they’ll ever be to ride on Helston and Dumoor, to confront the newly crowned King Peran and the Witch Queen, and finally define what peace truly means. And there is a single truth Callie and friends must cling to: The battle is still worth fighting even when victory seems impossible.
Before we get to the cover, here’s a note from author Esme Symes-Smith:
Dearest Readers,
All the way back in the beginning, I promised you a happy ending, and a light at the end of the darkness. Even though SIR CALLIE is a fantasy story full of magic and dragons, it has always been important to me that it feels real.
There were many times in writing where a happy ending felt impossible, and I struggled to believe in it for myself. Of course, as the author, I could give my characters a Happily Ever After in just a few words, but I wanted it to feel real. I wanted to leave you with the certainty that they’re going to be okay, not just in the last few pages, but long after the book is finished.
It’s hard to believe in happy endings right now, when everything I know to be good and true is ignored in favor of all the things I know to be bad. But I have come to learn that I am not at the end of my story, only the dark middle when everything feels hopeless and it would be so much easier to quit than to keep fighting. I feel the way Callie did, and Willow and Elowen and Edwyn. I feel like a kid in a grownup’s world, witnessing all the wrong and trying to be heard. It feels like a battle that I keep losing, over and over.
But, you know what? I’m going to get up and fight again, even if I lose. I’m going to keep speaking, even if no one hears me. And I’m going to keep believing that my story only ends when I’ve won. I’m just not at that part of the story yet.
Throughout my journey with SIR CALLIE, I have been reminded so many times why the fight is worth fighting, and what the happy ending looks like. It’s in the fierce hope of the readers, and it’s that hope which keeps my own kindled.
Everyone’s journey is their own, everyone has their own way of being a hero, and everyone’s happy ending is a little bit different with a single commonality: the right to live as yourself with those who see you and love you, all the way through.
Thank you for giving me hope.
Be brave, be kind, be you.
Love, Esme Symes-Smith
