On the frozen Kusanagi Peninsula, a remote spit of land the Kaigenese Empire calls its 'Sword,' the warrior houses have repelled the Empire's enemies for generations. None is more storied than the Matsuda clan, whose bloodline can manifest the Whispering Blade -- a sword of ice harder than steel. Fourteen-year-old Matsuda Mamoru has been raised to inherit that legacy and defend his homeland, certain of his purpose until a transfer student lets slip that much of the history he was taught is propaganda. His mother, Misaki, knows the truth better than most. Once a fighter and vigilante in the wider world, she long ago surrendered that life to become a dutiful wife in a cold marriage, burying her past beneath the silence expected of a Matsuda woman. When war finally reaches the peninsula the Empire swore it would never touch, both mother and son must confront what they have been told, what they have sacrificed, and what they are willing to lose. Set in the same universe as M. L. Wang's Theonite series but requiring no prior reading, this self-contained epic trades quest fantasy for an intimate study of family, grief, and the cost of devotion to a nation that lies to its own.
