Last Signal From Earth (Best Choice): The Sun is dying. Humanity has 22 years. And something in deep space is counting. (Paperback) (ISBN-13: 9798198720879)

The Sun is dying.

Not in billions of years.
Not naturally.
And not by accident.

When exhausted astrophysicist Dr. Ethan Carter discovers a catastrophic 4.2% drop in the Sun's neutrino output, the scientific community dismisses it as impossible. But the numbers don't lie.

Earth now has just 22 years before global temperatures collapse and the atmosphere freezes.

Then comes the second discovery.

A repeating sequence of prime numbers-broadcast from the outer darkness of the Oort Cloud.

Someone... or something... is out there.

And they may be killing the Sun.

Pulled into a classified government operation known as Project Aethelgard, Ethan is forced aboard the Odyssey, humanity's most dangerous spacecraft ever built-powered by an unstable directed-antimatter drive capable of tearing the ship apart in a single mistake.

His only companion?

Homer.

A highly advanced AI with a sarcasm problem, questionable emotional stability, and access to every secret humanity has buried.

As the Odyssey travels farther than any human has ever gone, Ethan begins uncovering a truth so horrifying it could destroy civilization before the cold ever reaches Earth.

Because the signal from deep space was never a warning.

It was a countdown.

Perfect for fans of Project Hail Mary, Dark Matter, Interstellar, and The Three-Body Problem, Last Signal From Earth delivers cinematic hard science fiction packed with terrifying realism, deep-space mystery, psychological tension, and edge-of-your-seat survival.
