Joe is a mean, swearing, beer-drinking android programming machine, but lately, his ancestor keeps making him time travel back to the Ice Age to help her fight off an incursion from a local village.

They may have spears, but the Chieftain known as Bear has a secret weapon: Joe.

Plus the Internet. But on top of that, apparently technology similar to the mysterious vial Bear uses to pull Joe's consciousness back to the past is showing up both in the past and in the present in the form of strange robots.

What is their interest in Joe and his bloodline?

Blood Calls is an ongoing Newcomer World story.
