Sister's Blood Trigger

The gun on my arm isn't a weapon anymore. It's a mouth, and it's learning to speak with my dead sister's voice. Three years ago I burned out of the government's ghost squad with a rune-weapon fused to my nerves and a name I couldn't say out loud. I told myself the nightmares would fade. Then Marcus Rein — the man who trained me, who left me bleeding in that lab — kicked in my door at 2 a.m. with a new mission: hunt down the rogue bioweapons breeding underground. Their designations are the ones I memorized in my sleep. They were my team. The first target I corner isn't a monster. It's Zero — my old partner, what's left of him — and he screams my sister's name like a wound reopening. My arm lights up blue, hungry, and for one second I can't tell if the trigger-finger is mine or the weapon's. Ash, the rookie who still believes in clean orders and good men, watches me hesitate and starts asking questions Marcus never wanted asked. Every file I dig up says my sister's "death" was the lie that built this whole program — and that the rune eating my body was cut from her flesh. I have a gun that wants my soul, a handler who wants my compliance, and a ghost wearing my sister's voice begging me to choose: pull the trigger, or finally find out how far I've already become one of them.
