During the Decade of Plagues, pandemics brought civilization to a standstill. The only way out was the Aspis chip: a wearable mRNA vaccine factory, able to immunize you against new viruses on the fly. But not everyone wanted it. They created an open alternative: Darkome, an underground community of biohackers modifying their own genes and bodies. Inara came of age in a Darkome village - but only an Aspis could keep her rare cancer in check, updating her immune system at a pace with her cancer's evolution. Accepting it went against everything Darkome stood for. She had to choose between her community and her life. Now Inara's Aspis appears to have malfunctioned.

She can edit her own DNA to be stronger, faster, smarter. It could be the genetic breakthrough of the millennium, but only if she can figure out how it works . and to stay ahead of those who will stop at nothing to possess her secret. Pursued by Aspis, Darkome radicals and the government, her new abilities may be the only way for Inara to survive. But they may cost her everything, including her humanity.
