 The flickering neon sign of the Crimson Dragon casino reflected in the oily puddle at my feet, the smell of synth-noodles and desperation thick in the air. I flipped the platinum coin – not currency, but a memory chip containing Luna’s digitized consciousness – and caught it with a practiced flick of the wrist. Victor owed me more than just money; he owed me *her*. Tonight, I collect. And if the rumors about his new "bio-engineered enforcers" were true, tonight’s payment would be in blood.
