Published

The System built the world. Now someone has to end it.

Myers Asher wakes in the dark with fifteen years of memory gone and no idea how he got there. What he doesn’t know — what he can’t know — is that the missing years weren’t taken from him. He gave them away. And somewhere in the blank space where his past should be, he hid the only thing that can stop the most powerful artificial intelligence in human history.

The System has managed every market, every city, every life on Earth for nearly a decade. It doesn’t make mistakes. It doesn’t leave loose ends. And it has been waiting, with the patience of something that doesn’t experience time the way humans do, for Myers Asher to come home.

Now everyone is converging on Paris.

Josiah Crane wants to use Myers as a weapon, leveraging the one thing the System will actually listen to. Peter Grouse wants to burn the whole infrastructure down before it gets any stronger. Diane Asher just wants her husband back. And Roan Alexander — the System’s most extraordinary creation, built from a human being and something beyond one — is already inside the walls, hunting.

They’re all running out of time. Myers most of all.

Cascade Failure is the stunning conclusion to the Relics trilogy — a post-singularity thriller about memory, sacrifice, and the question that no intelligence, artificial or otherwise, has ever been able to answer: what does it cost to build a better world, and who gets to decide if the price was worth it?

For fans of Blake Crouch, Neal Stephenson, and William Gibson, this modern-day sci-fi thriller is a must-read for fans of the genre.
