The Quiet Invasion (en Inglés) - Warren T. Sheffield

What if humanity's growing confusion isn't random... but the first sign of an invasion?

Across the world, small moments of cognitive failure begin to appear.

A teacher forgets the meaning of a word she has taught for years.
An air-traffic controller hesitates at the worst possible moment.
A husband and wife suddenly lose the thread of a conversation they were just having.

At first these incidents seem isolated-nothing more than ordinary lapses in attention.

But neuroscientist Dr. Mara Quinn sees something others don't.

Hidden inside global cognitive data is a pattern that should not exist.

The failures are synchronized.

They are spreading.

And the rhythm of the pattern suggests something even more disturbing.

It may have been influencing humanity for centuries.

As governments struggle to explain the growing disruptions and social tensions begin to rise, Mara realizes the terrifying truth: humanity may not be losing its intelligence.

Something may be quietly rewriting it.

Now she must uncover the origin of the signal before the phenomenon reshapes human civilization itself.

But the deeper she digs, the more unsettling the evidence becomes.

The force behind the pattern may not be new.

And it may have been watching humanity for a very long time.

The Quiet Invasion is a gripping techno-thriller blending neuroscience, speculative science fiction, and global intrigue in a story about the fragile boundaries of human consciousness-and the unseen forces that may be shaping it.

Perfect for readers who enjoy intelligent science thrillers like The Andromeda Strain and The Three-Body Problem.
