The Dinosaur Lords by Victor Milán

In a province of pacifists a former mercenary lord must raise an army aided by the dinosaur master who once helped defeat him. In the court of the Empire of Nuevaropa, the imperial princess Melodia struggles to free herself from the shadow of her loving, and oblivious, father while her betrothed. the dashing Count Jaume, is forced by his own sense of duty into a course of action where no choice will be the right one.

This is the world of Paradise where the schemes and passions of men are played out in the courts of power and on the battlefield. Where the weapons are words, swords, and dinosaurs.
