Camilla stepped forward more deliberately, keeping her eyes on the Prince’s eyes. Palamedes said, “For heaven’s sake, Nav, lay off the grandstanding,” but Camilla took the Prince’s wrist, positioned the needle, and pushed the syringe decisively home.
The needle snapped in half, like she’d jabbed it into the tiled floor. Camilla staggered back as if this had thrown her off-balance. Kiriona Gaia opened her hand—moved it to steady Camilla’s shoulder—then, like she was flinching, roughly shoved her away. Camilla fell back into Palamedes’s arms.

“My father has made my body’s bones denser than titanium plex,” said the Crown Prince coldly. “My father has made my skin turn away bullets. I am the perfect sword hand and the final expression of the art of the Nine Houses. Don’t you get it? I am the Emperor’s construct.”
