The Escapement by KJ Parker (Engineer Trilogy #3) (Paperback)

Sentenced to death, the engineer Ziani Vaatzes managed to escape from Mezentia. His unyielding determination to return home drove him to devise a complex scheme to overthrow the Republic, a plan that would necessitate a war. He deeply regrets the loss of lives, but he felt he had no alternative.

Duke Valens reluctantly plunged his people into the war in a desperate bid to save one woman’s life. Tragically, he ended up taking the life of her husband. Now, aligned with nomadic barbarians who possess the numbers to defeat Mezentia, the Duke is haunted by remorse for his wrongs. However, he, too, felt trapped with no other options.

Secretary Psellus never aspired to rule the Republic or engage in a harrowing siege to ensure its survival. As he grapples with the bewildering turn of events, he finds himself compelled to delve into the circumstances surrounding Vaatzes’ crime. He is terrified of what he might uncover, yet it seems he has no other course of action.

The machinery has been constructed. All that remains is to set it into motion.

This marks the breathtaking conclusion to The Engineer Trilogy, a fast-paced blend of politics, action, and intricate world-building that continually pushes the boundaries of fantasy fiction.
