Run.

The sirens have burned out. Streetlights blink like dying eyes. They don’t shamble. They sprint.

Annie Schwartz—sixteen, brilliant, stubborn—counts exits and keeps her little brother breathing. She sees patterns the way others see faces. The city is a puzzle. The puzzle is bleeding.

Somewhere, eco-terrorists hijacked the vaccine’s code and opened a door the world can’t close. The flu shot became a fuse. Every hour, the swarm grows. Every day, the update pings to another town. If Annie can’t crack the signal, the map goes red.

Finding the source means stepping into the storm: a lab charred to bone, a manifesto written in ash, a kill switch humming inside a lullaby. Allies she can’t trust. A boy she can’t lose. And a choice that could save millions—or save one.

Run.

The bodies are wired to the clock. The cure cuts as deep as the disease. Because when the world is the trap, intelligence is a blade—and blades draw blood.

She can end it. She can save him. She cannot do both.

How far will she run before something faster finds her?
