Lastborn

A huge comet enters Earth's atmosphere at a blistering 67,000 miles an hour. It is a cosmic bomb of epic proportions, destined to snuff out 97 percent of all earthlings, both plant and animal. Lastborn, a dinosaur, has inherited a set of traits know as the Gift, which includes an oversized brain, extra-sharp senses, and odd-colored eyes and skin. To the others, he's a freak. He might have spent all his days as an outcast, but for the comet that slams into the earth. When the ground explodes beneath them and the sky catches fire overhead, the dinosaurs' known world is dramatically altered. In this time of desperation, the Gift could mean the difference between survival and extinction. Lastborn has the ability to guide his tribe through the cataclysm, but only if they let him.
