Deadlands book 1: Hunted

When the Fallen Star struck, it brought death and despair, ash and toxic rain. But some dinosaurs survived . . . and were changed. Their minds grew alert. They learned to speak. To dream. To wage war. As the two remaining dinosaur kingdoms fight for territory, Eleri, the disgraced son of a prince, is exiled from his home for saving an enemy. Banished to the Deadlands, a terrifying desert full of tar pits, poisonous gas, and ruthless carnivores, he must join forces with a group of questionable allies—including the enemy he saved—to avoid becoming prey. When Eleri and his fellow exiles discover the horrific truth behind the war, the unlikely heroes must do all they can to save their kingdoms from a lurking predator . . . and a secret plot that might destroy them all.
