4.5, I loved this. I'd say 5 in a different mood, even. RTC.
Later: The premise here is perhaps cringey to a certain type of reader: in a near future containing “driverless ubers” but no New Zealand (casualty of a nuclear exchange with North Korea, apparently), Jared, a bot who looks exactly like a human but whose brain is a biological computer and who has no emotions, begins to develop feelings, along with a taste for classic movies. Pursued by an incompetent but dogged jobsworth from the Bureau of Robotics, he flees his comfortable, sterile dental practice in Ypsilanti for Los Angeles, intending to write and direct a movie that will change the way the world feels about bots. So far, perhaps, so cute (an impression backed up by Jared’s relentlessly slangy narration: “10/10” and “I cannot!” being but two of his many catchphrases). But what makes this stand out as more than just a big-hearted underdog novel with futuristic set dressing is its obsession, nay its love affair, with film tropes—which are, of course, storytelling tropes—and by way of which Jared comments, both explicitly and unconsciously, upon his own quest.
I wrote “underdog” up there, for instance; Jared knows he’s in a quest story, and he knows how the logic of such stories works. He knows that Inspector Ryan Bridges of the Bureau of Robotics is his nemesis, and that (as per RP McWilliam’s Twenty Golden Rules of Screenwriting, a text he treats with reverence) coincidences should only occur in order to create obstacles, not to smooth the hero’s path. This incredible circular knowingness—a story about stories, and who gets to tell them, and how they can be hijacked (there’s a great subplot about an unscrupulous Hollywood producer), which also knows it’s a story, and comments on that, and the comments are both an integral part of the story and reinforce its thematic meaning—is quite brilliant, and further reinforced by form, as sections of the book are typeset to resemble a film script. If this all sounds a bit precious, please trust me when I say that it is not. There is something perfect and painful about Jared’s first viewing of Blade Runner, for instance—quite deliberately a movie about whether robots are people—or about his being reassured that the people sailing on Lake Michigan during inclement weather probably don’t want rescuing, because humans actually enjoy illogical risk. Not to mention his unexpected side trip to Las Vegas with a lonely, self-deluding fellow train traveler (who happens to hate bots), or the way he falls in love. Set My Heart to Five is poignant, funny, light on its feet, and very, very sharp. By the end, I felt—as Jared hears a famous screenwriter say—as though I’d been “f-worded in the heart”; I can’t recommend it more highly.
