Causal Chain. A Deep-Space Time Travel Thriller (en Inglés) - Jason Thomson

The mission to Pluto proved time travel was possible.
What it brought back may destroy the future.

Six weeks after the crew of the Threshold survives an impossible journey through time, Dr. Elise Navarro and the others are trapped in the machinery of official review, secrecy, and institutional control. The world knows they returned from deep space. It does not know what really happened.

Hidden inside the ship's AI is an archive no one was meant to find.

It contains fragments from the past. Signals from the present. Warnings from a future that may already be collapsing. As Elise, Commander Vosler, Tomer, Malik, Cross, Soren, and Renn begin to uncover the truth, one terrifying possibility emerges: someone knew the mission would fold through time before it ever launched.

And they sent the crew anyway.

Now the archive is growing. Governments want control of it. Scientists want to study it. Powerful officials want to bury what it reveals. But the deeper the crew digs, the more dangerous the pattern becomes. The archive is not just a record of what happened.

It may be part of the chain that causes what comes next.

With the future warning of catastrophe and the present racing to exploit the impossible, Elise must confront the question at the heart of every paradox: if they expose the truth, do they save the future, or create the disaster they are trying to prevent?

The Causal Chain is a tense, intelligent deep-space time travel thriller about AI, conspiracy, institutional power, and the terrifying cost of knowing what comes next. Book Two of the Time Fold Trilogy.
