About the Book

In 1984, Turing Award winner Ken Thompson revealed that a compiler
could be modified to insert an undetectable backdoor into every
program it builds--and that no one could ever be sure it hadn't been
done. METACOMPILER is the novel about what happens when someone
proves it was.

Kaliya "Kali" Devi was born deaf and blind. Her neurosurgeon father
fitted her with cochlear implants at two and an experimental optic
nerve interface at twelve, giving her the ability to perceive the
electromagnetic spectrum--to hear WiFi, see data, feel the
computational heartbeat of every device in range. When her fiance's
car is remotely commanded to accelerate on a California highway, Kali
discovers a compiler-level backdoor that has existed in every
computing device on earth since the 1970s, now weaponized by Russian
military intelligence into a system that can kill through any
connected machine.

To destroy it, she must build a clean compiler from scratch,
construct a distributed supercomputer from hundreds of thousands of
hijacked devices, and answer the question her allies keep asking: How
are you different from the people you're fighting? The answer will
require her to create the world's first artificial general
intelligence--not as a weapon, but as a child.

"The most technically accurate depiction of a compiler-level supply
chain attack I have read in fiction."
"This is what Brad Taylor would write if he understood computers."

How It Was Built

METACOMPILER was written by a team of AI agents under the direction
of embedded systems expert Michael Barr. Using Claude Code by
Anthropic, Barr built an orchestration system with three AI writers,
three editors, and four specialized reviewers--producing 43 chapters
in twelve hours, then spending weeks editing, rewriting, and fixing
the things AI gets wrong.

A novel about the birth of AGI, built by AI, directed by a firmware
engineer. The narrator is the AGI the protagonist creates--telling its
own origin story from the future.
