This is book number 1 in the The Dinosaur Lords series.
"It's like a cross between Jurassic Park and Game of Thrones." —George R. R. Martin
A world made by the Eight Creators on which to play out their games of passion and power, Paradise is a sprawling, diverse, often brutal place. Men and women live on Paradise as do dogs, cats, ferrets, goats, and horses. But dinosaurs predominate: wildlife, monsters, beasts of burden–and of war. Colossal plant-eaters like Brachiosaurus; terrifying meat-eaters like Allosaurus, and the most feared of all, Tyrannosaurus rex. Giant lizards swim warm seas. Birds (some with teeth) share the sky with flying reptiles that range in size from bat-sized insectivores to majestic and deadly Dragons.
Thus we are plunged into Victor Milán's splendidly weird world of The Dinosaur Lords, a place that for all purposes mirrors 14th century Europe with its dynastic rivalries, religious wars, and byzantine politics…except the weapons of choice are dinosaurs. Where vast armies of dinosaur-mounted knights engage in battle. During the course of one of these epic battles, the enigmatic mercenary Dinosaur Lord Karyl Bogomirsky is defeated through betrayal and left for dead. He wakes, naked, wounded, partially amnesiac–and hunted. And embarks upon a journey that will shake his world.
