From the introduction: Life’s been pretty good for giant reptiles over the last thousand years or so, but lately something hasn’t been quite right. There’s a weird burny thing in the sky different from the usual weird burny things, and there’s an itch deep down in your lizard brain that urges you to run. Instinct gives you no direction in which to run and even if it did, there’s no place to run TO. The sky is on fire and the ground shudders beneath your claws. Something big exploded far away, and it’s bad news. This is the end. Or is it?
