Existence

What if first contact wasn't an invasion… but a warning? A silent craft appears above Washington, D.C.--then vanishes without a trace. Within hours, identical apparitions sweep across the world's capitals, shaking governments, religions, and militaries to their core. No weapons fire. No demands. Just a presence so advanced it defies physics--and understanding.

I did not see THAT coming!

It was perfect! The battle of the AI's. Good vs. evil. Whew! Nicely done.

Existence is essential reading

I loved the pace and message of this timely book. Bill Brown uses a tense, exciting story to give a warning to all of us about saving our planet. He exposes the primary reason our current environmental crisis is not being addressed. He crafts a real-life scenario of the consequences of greed and the quest for power. This is one of Brown's best!

Hooked me from the first page. Excellent science fiction mystery full of suspence and danger. The fate of the Earth is at stake. Loved the main characters including their romantic involvement. I want more!!

(Note: Bill is still working on Existence. He says it’s practically writing itself, and he’s excited to finish.)

At the center of the mystery is David Browne, a junior congressional aide who should never have mattered to events of global consequence. But one careless experiment with a cutting-edge artificial intelligence program opens a door humanity was never meant to unlock–a bridge between realities.

Now David is being followed by something that looks like him… speaks like him… and knows his thoughts.
As world leaders scramble to avoid catastrophe, David discovers a terrifying truth: the visitors are not aliens in the traditional sense. They are humanity’s successors, evolved versions of ourselves from parallel realities that share the same Earth–and the same fate. And they have come to pass judgment.

Humanity is destroying the one constant that binds all realities together: the planet itself.
With time manipulated, physics rewritten, and entire military bases erased without a trace, David finds himself thrust into the most important conversation in human history. The visitors have issued an ultimatum. Humanity has 28 days.

Change–or be removed.

Blending hard science fiction, political thriller, and philosophical speculation, Existence explores artificial intelligence, parallel universes, environmental collapse, and the terrifying question at the heart of modern civilization:

What if saving humanity means becoming something else entirely?
