Nemesis (Resident Evil #5)

It's in your blood Zombies, mutant animals, bioengineered weapons and surgically enhanced monsters: after all she's been through, Jill Valentine is ready to leave Raccoon City forever. But the Umbrella Corporation isn't going anywhere... yet. Evidence of their insidious genetic experiments still exists, and it must be recovered—or destroyed—before it can be traced back to the sinister corporation. As a mutagenic virus spreads through the city, mercenary teams sweep in, along with something else—a lethal creature code-named Nemesis. Nemesis is on the hunt, and Jill Valentine is about to become its prey.
