About the book

The Sword of Kaigen is an adult high-fantasy novel set in a Japanese-inspired warrior village on the edge of the Kaigenese Empire, in a world where people called Theonites can manipulate the elements. It centers on two members of the legendary Matsuda family: fourteen-year-old Mamoru, raised to master his clan's water-and-ice fighting techniques, and his mother Misaki, who buried her adventurous youth when she married into the rigid Matsuda household. When an outsider casts doubt on the empire's supposed age of peace and the threat of invasion looms across the sea, both mother and son are forced to confront what they have been taught and who they truly are.

Beneath its martial-arts spectacle, the book is a character-driven exploration of family, grief, duty, and the cost of suppressing oneself to fit a role. It examines the constraints placed on women within a patriarchal warrior culture through Misaki, while Mamoru's arc probes loyalty, propaganda, and the gap between national myth and reality. Wang pairs an elemental magic system with intimate domestic drama, treating loss and resilience as seriously as combat.

Originally self-published in 2019 as a standalone companion to Wang's Theonite series, the novel became a word-of-mouth success and won the fifth Self-Published Fantasy Blog-Off (SPFBO), one of the contest's highest-scoring entries. Reviewers widely praised its emotional depth, its mother-son relationship, and its action set pieces, and the book has maintained a very high reader rating, helping establish Wang's reputation in the fantasy community.
