Nanite and implant internal technology began in the Pax Romana planetary empire's army, but it hasn't stayed there. Across four novellas and more than a century, two natives of the conquered planet Idyll must each contend with technological abilities thrust upon them without their consent.

Genevieve, living in a time of war on her planet, was infected with nanites from a dying super-soldier-nanites that remade her in the image of those super-soldiers. Sienna, caught between the now-aging empire and even more violent rebels, was captured and used in a prisoner exchange in the place of a dead Pax Romana spy-leaving her with that spy's implant in her head, leaking memories.

Can Genevieve and Sienna remain themselves with internal technology taking over their minds? And what can they do when the abilities granted by that hated technology are the only thing that can save the ones they love most?
