"They hunt the scent of emotion. He's serving vengeance." A family dinner. The warm aroma of home-cooked food. One knock-and everything shatters. A masked creature drags Aiko's mother into the dark, spits out their meal, and murders his father. The air reeked of iron and burnt spice-the smell Aiko will never forget. Years later, Aiko hides in plain sight-working for a covert agency that studies the aromas monsters crave. By day, he cooks to lure them in. By night, he hunts them down. But the creature who destroyed his family isn't alone... and tonight, the scent of death is back on the wind.
