They knew they weren't alone... but they weren't expecting this.

Cade and his friends explore their dangerous new world. Shy Ones attack. And then something bigger appears: a ten-meter-tall robot. It shepherds the Shy Ones away. It claims to be their friend.

And when one of Cade's friends suffers a terrible injury, he's forced to trust that the robot can help them. But there's something off about their Silver City, something strange and almost sad about the Shy Ones. Something secretive about the robots. So how much can they trust this mysterious being?
