Wholeness, she had learned, was not the absence of pain but the ability to hold it.
On a mountainside at the edge of the Kaigenese Empire live the most powerful warriors in the world, superhumans capable of raising the sea and wielding blades of ice. For hundreds of years, the fighters of the Kusanagi Peninsula have held the Empire’s enemies at bay, earning their frozen spit of land the name ‘The Sword of Kaigen.’
Born into Kusanagi’s legendary Matsuda family, fourteen-year-old Mamoru has always known his purpose: to master his family’s fighting techniques and defend his homeland. But when an outsider arrives and pulls back the curtain on Kaigen’s alleged age of peace, Mamoru realizes that he might not have much time to become the fighter he was bred to be. Worse, the empire he was bred to defend may stand on a foundation of lies.
Misaki told herself that she left the passions of her youth behind when she married into the Matsuda house. Determined to be a good housewife and mother, she hid away her sword, along with everything from her days as a fighter in a faraway country. But with her growing son asking questions about the outside world, the threat of an impending invasion looming across the sea, and her frigid husband grating on her nerves, Misaki finds the fighter in her clawing its way back to the surface.
When the winds of war reach their peninsula, will the Matsuda family have the strength to defend their empire? Or will they tear each other apart before the true enemies even reach their shores?
A rich elemental magic system and deep world-building make this martial fantasy perfect for fans of R.F. Kuang, Brandon Sanderson, Leigh Bardugo, and Lian Hearn.

More About the Story
The Sword of Kaigen is a military fantasy that takes place thirteen years before the events of Planet Adyn and Orbit in the Shirojima region of the Kaigenese Empire. It is a standalone novel, meaning that you do not need to have read the Theonite books to appreciate it.
This story originated as a serialized story that I released to my newsletter subscribers in monthly installments. When I realized that it had overgrown its bounds into a novel longer than Orbit, I decided to complete the story and publish it ahead of the newsletter installments.
Unlike the younger-skewing main Theonite Series, The Sword of Kaigen falls firmly into high fantasy territory, dealing with more difficult themes and subject matter through older POV characters. I don’t like to impose restrictions on anyone’s reading but I would not recommend SoK to readers under the age of sixteen.
