The multiverse is collapsing. The time machine is broken. And humanity's last hope? Might already be dead.

Seven months after the EMPs brought the world to its knees, a handful of scientists are racing against extinction?and each other. Somewhere in a flooded skyscraper lies a wormhole generator that might be able to undo the apocalypse. If they can find it. If it still works. If it doesn't kill them first.

Meanwhile, Diego Nadales wakes up chained to a wall, his face bloodied and his memories fractured. He's being accused of terrorism, treason, and time travel. The last one, at least, is true.

Isabel is trapped inside a biodome ruled by the man she once trusted. But her bees?microscopic drones designed to save the planet?have been hijacked and weaponized. If she doesn't find a way out soon, her creation will wipe out the last threads of life on Earth.

Old friends return. New enemies rise. And somewhere in the chaos, one small spark of hope just might be enough to ignite a revolution.

The clock isn't ticking. It's broken.
