Odys Odelyn is given a coin by a mysterious man named Pepin Pound just before the man kills himself. The coin is the inanimate form of an Automaton - a creation of the god Vulcan. She is one of nine such creations that the god has left on the earth after serving her previous purpose. Pepin had to kill himself in order to free her for a new Master. Humans with Automata are called Masters, and the Automata are activated by the Master's soul and are just another vessel for their Master, yet with the knowledge and memories of their previous Masters. There is a rogue Master, Leeland, wanting to collect all the Automata under one Master because he believes they are evil and create strife when held individually. The other Masters have banded together to protect themselves, but their organization is threatened when Vulcan hints at a new plan for his creations - one that has been using all their actions and feuds to further his grand designs.

The Narrator of the book claims to be a character in the story, though does not reveal their identity until the end. The Editor, Gabbler, claims to know the Narrator personally and believes the story to hold literary merit and contain half-truths. Their genders are kept hidden.

Publishers Weekly called the book "amusing," though noted that the meta nature of the novel could draw the reader away from the underlying story.^[4] BookLife picked up the book for review and selected it for a complementary curation in PW Select.^[5][6]

Tales of the Talisman gave The Automation 4.5 talismans out of 5, and observed that the characters "are being manipulated by the author and editor, who break the fourth wall in running commentary that bounces between text and the footnotes..." and that the story brings "the gods into the modern world."^[7]

Author Adam Oster calls The Automation "a hard book to categorize. It’s a little experimental, a little goofy, and a little science-fiction-y, while also hosting a bit of Greek myth and hard boiled detective novel-style narration."^[8]

The novel has also garnered many reviews from niche bloggers^{[9][10][11][12][13][14][15][16][17][18]} and verified reviews on Amazon.^[19]
