What it feels like

This is a fantasy that takes its time building a quiet, suffocating atmosphere of domestic duty and youthful naivete before shattering it entirely. The narrative begins with a steady, deliberate focus on family dynamics and the weight of hidden pasts, wrapping the reader in a wintry, melancholic mood. When the inevitable violence finally breaks, the pacing accelerates into some of the most visceral, kinetic elemental combat in modern fantasy, but the true devastation is entirely emotional. It is a story that strips away the glory of war and the lies of empire to expose the raw, bleeding heart of a mother's grief and a family's fractured bonds. Readers who love character-driven epics that leave them emotionally hollowed out yet deeply satisfied will find themselves completely consumed by this masterful, heartbreaking journey.

About the book

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?
