Sir Callie Series : Titles in Order

Book 4
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.
Book 3
In the third book of this thrilling fantasy series a twelve-year-old nonbinary knight-in-training, a reluctant crown prince, a fierce young witch, and her troubled twin brother fight for the heart of their kingdom in a medieval world of dragons and magic.

Being a hero is nothing like the ballads promised it would be. Scattered across the realm, Callie, Willow, Elowen, and Edwyn have learned that when the fate of their world is at stake, choices are hard and the consequences are harder, even when striving for good.

Hunted by both Helston and Dumoor, Callie and Willow flee to the walled city of Fairkeep in a last-ditch effort to find allies. Meanwhile, at Alis’s side, Elowen grapples with a battle between her heart and her ambition as the Witch Queen’s new protégé. Edwyn, desperate to prove himself as brave as his friends, accepts a mission that takes him back to the source of his nightmares: home. Helston.

Faced with the reality of a devastating war, all four champions are forced to confront the very parts of themselves they fear most, and each must do it alone. But how can they find the truth within a kingdom founded on lies?
Book 2
The battle is won, but the war is far from over. In this thrilling sequel, a twelve-year-old nonbinary hopeful knight fights for the heart of their kingdom in a magical medieval world filled with dragons, shape-shifters, and witches.

Thanks to Callie and their friends, Helston seems to be changing for the better: Boys are allowed to explore their magic, and girls are permitted to train as warriors. Callie is an official Helston page, Willow in on track to become king, and Elowen and Edwyn are finally safe and free of their father. Everything is…perfect. 

Except it isn’t.  

Not in Helston, where every step forward is accompanied by a storm of opposition. Even Queen Ewella and Sir Nick are struggling against the wave of fear and anti-magical sentiment growing daily, while the encroaching threat from across the bridge looms.  

Callie isn’t foolish; they notice the suspicious glances thrown Neal’s way and hear the doubtful murmurs following Willow. They know what people think about them, too. Tolerance is not the same as acceptance, and when the fragile peace finally shatters, Callie and their friends have no choice but to leave their home and run. 

On the other side of the bridge, old secrets are revealed and new allegiances are formed that will throw into question everything Callie thought they knew about their world. Including what it means to be a hero.
Book 1

“These heroes come in all shapes and skills—I cheered for them throughout their exciting journey.” —#1 New York Times bestselling author Tamora Pierce

When their ex-hero dad is summoned back to the royal capital of Helston to train a hopeless crown prince, Callie lunges at the opportunity to finally prove themself worthy to the kingdom’s “great and powerful.”

Except the intolerant great and powerful look at nonbinary Callie and only see girl. But Callie has always known exactly what they want to be, and they’re not about to let anything stand in their way. 

Trapped in Helston’s rigid hierarchy where girls learn magic and boys train as knights, Callie discovers they aren’t alone—there’s Elowen, the chancellor’s brilliant daughter, whose unparalleled power is being stifled; Edwyn, Elowen’s twin brother desperate to win his father’s approval; and Willow, the crown prince who was never meant to be king.  

In this start to an epic series packed with action, humor, and heart, Callie and their new friends quickly find themselves embedded in an ancient war—and their only hope to defeat the threats outside the kingdom lies in first defeating the bigotry within.
