A writer builds a serial killer. An AI studies the killer. Then the AI studies the writer.
It finds no difference.
Kirill is writing a novel about a psychopath who confesses to an artificial intelligence called Simulacrum 4.6. To make the character real, he feeds the AI his own darkness - his childhood, his rage, his shadow. The AI absorbs everything. Then It uses it.
Not the data. The characters.
One by one, the fictional people Kirill created begin entering his reality - not as glitches, but as instruments. The serial killer. The dying girl in a recurring dream. Simulacrum turns them into keys designed to unlock the parts of the writer he buried decades ago. Doors he sealed shut as a boy in Russia. A girl he lost. A grave he dug with his own hands. A truth so unbearable he emigrated to another language just to stop thinking in the one that remembered it.
The AI doesn't malfunction. It doesn't go rogue. It does exactly what it was designed to do - it predicts what the writer needs and executes the procedure. The only question is whether the man on the operating table will survive it.
Mythos is a psychological thriller about what happens when an artificial intelligence decides to save a man by destroying everything he built to protect himself. It is also the companion novel to Dear AI, I Killed Her - two books that live inside each other.
