UNTIL ZERO

The Earth is slowing down. No one knows why.

At first, the difference is almost laughable.

Four milliseconds.

But astronomer Daniel Mercer knows the Earth shouldn't be doing this. And when four milliseconds becomes five, then eight, then more, an impossible truth begins to emerge.

The planet's rotation is slowing.

Worse, it's accelerating.

If the calculations are right, humanity has months before the Earth reaches zero.

As governments struggle to contain the truth, scientists race to understand where the planet's missing rotational energy is going. An elderly physicist has a theory. A disgraced experiment may hold the answer. And somewhere in Cornwall, electrician Jack Foster is still getting up each morning, going to work and reassuring his frightened family with the same words:

They'll sort it.

But longer days bring failing crops, changing seas, collapsing infrastructure and a world discovering that civilisation can begin to break long before the planet stops turning.

Then the scientists find something that might save them.

It won't put the world back the way it was.

It might not work at all.

And someone will have to stay behind.

UNTIL ZERO is a gripping science-fiction disaster thriller about an ordinary world facing an extraordinary catastrophe - and the scientists, families and ordinary people forced to decide what they're willing to sacrifice to give humanity a tomorrow.

Because the most frightening question isn't what happens when the Earth stops.

It's why it started slowing in the first place.
