About this book:

*The Siegewright* tells the story of Mara, a mason’s daughter who possesses a profound, technical understanding of stone and structural engineering. When war comes to the border keep of Torvall, Mara is thrust into the role of de facto defense commander. While the keep’s lord, Sir Edwen, and his ambitious cousin, Sir Aldric, focus on the optics of chivalry and vanity—specifically the construction of a strategically useless tower—Mara focuses on the "dull heroism of maintenance." She meticulously catalogs structural weaknesses and organizes a "Women’s Corps" to monitor the keep’s respiratory and physical health, proving that the true strength of a fortress lies in its invisible infrastructure.

As the northern lord’s army begins a protracted siege, Mara outmaneuvers both the enemy and the internal political posturing of the court. She counters a subterranean mining attempt with a precision-engineered counter-mine, neutralizes trebuchet fire using "falsework" and angled glacis slopes, and stabilizes the gatehouse with harmonic counterweights. Throughout the conflict, she faces constant skepticism from men who mistake her data-driven pragmatism for a lack of vision, eventually exposing Sir Aldric’s incompetence and deceptive reporting.

The narrative reaches its peak during a brutal winter that tests the keep’s "winter load." Mara adapts the fortress into a living system of survival, moving grain into the chapel and sealing flues to prevent smoke inhalation. By prioritizing the physics of endurance over the glory of battle, she forces the enemy to retreat. In the aftermath, Mara is offered a prestigious title in the south but chooses to remain at Torvall until its "wounds" are fully healed. The book concludes as a meditation on the labor of women and laborers whose quiet contributions form the literal and metaphorical mortar that holds society together.
