Intravenous

Two sets of twins. One mother who never learned where science should stop. When one sister is secretly experimented on by her scientist mother, her twin grows up untouched, becoming a cop who survives by turning trauma into graphic novels. Years later, a crime shatters what's left of the family. As control devices, manipulation, and buried experiments resurface, the line between protector and weapon collapses.
And when the youngest survivor wakes from a coma, something else wakes with her. Something no longer entirely human.
