K. J. Parker writes fantasy about engineers, soldiers, bureaucrats and ambitious people whose practical solutions often create larger political problems. The Engineer Trilogy, beginning with Devices and Desires, builds warfare around machinery, design and revenge rather than magical prophecy. Sixteen Ways to Defend a Walled City follows an engineer trying to organise an apparently impossible defence during a siege, using logistics, improvisation and unreliable self-justification as much as combat. Parker's shorter novels and stories frequently turn on contracts, economics, craftsmanship and the unintended consequences of clever plans. The tone is dry, cynical and often funny, with little interest in conventional heroic purity. The books fit military fantasy, low-magic fantasy and engineering-driven speculative fiction.
