Burning Day by Viola Grace

A human colony preparing to celebrate three hundred years on its new world is suddenly faced with an enemy that hearkens back to their early days on Hera.

The giant bots that saved the colony have been dormant for nearly two centuries. During a celebration that proves the engineers have kept them ready for battle, the party turns into a race to save lives and get to the bots.

The engineers have been responsible for the mechanical stability of the bots. They are not pilots. The pilots are in the city, two hundred kilometers away. There are six surviving bots and six engineering clans that care for them. It is up to the engineers to get the bots up and running so that they can get the right pilot for the right job. If they can get the bots moving.

Six women, six stories, and six very different AIs giving them attitude.
