Sailing the Indian Ocean as a city without government influence, the Bastion of Ceres runs a powerful trade route with a dedicated crew and a stalwart commander. As any city, the massive ship contains everything the employees of Konïgstød Industrial need to survive and thrive, but it also has found itself in the sights of the Altruistic Society of They.

Seraphine, a spy hired by They, has snuck aboard the massive ship, assuming the mask of a lowly private, with her mind set on cruel intentions. They are set on crippling Konïgstød's ability to control trade in the region, and Seraphine is dedicated to the cause for personal reasons.

Fortunately for the Bastion of Ceres, Technical Sergeant Felicity Barwood is a mechanical savant and a miracle-worker with a wrench. When the skilled technician begins to notice things going awry on her home, she springs into action.

Though her personal life and the people she loves are about to get dragged into a dangerous game of cat and mouse. As well, a revelation about her future will threaten to sideline the one person on the Ceres who can undo all of Seraphine's schemes.

Will Felicity be able to keep her floating home in one piece, or will the plots of They bring an end to Konïgstød's power on the Indian Ocean?. .
