They are saurians.
They are armed and dangerous.

On an Earth where the descendants of dinosaurs are still the dominant species, human beings have only their ingenuity to pit against the terrifying biological technology of the Yilanè. Kerrick grew up as their slave-pet: now he must rescue his embattled people with the help of the seafaring Paramutans. And in order to succeed he must place the future of the entire human species at risk...

Winter in Eden continues Harry Harrison's acclaimed epic story of the titanic clash between two implacably opposed cultures - the saurian Yilanè and the resourceful mammals who have dared to challenge their absolute power.
