THE VACUUM WE RETURN TO

by Tsung-Long Wu ‧ RELEASE DATE: May 30, 2026

In Wu’s SF novel, a peculiar phenomenon pulls a couple into a high-stakes conspiracy.

Firefighter Hope Valentine has spent more than 15 years learning to understand the movement and behavior of fires, but nothing prepares him for the life-changing evening when he witnesses a fire “un-burn” itself. During a rescue, the flames are pulled backward in “slow reverse” down a hallway before continuing onward again. It’s an impossibility that he can’t shake—can such a twist in reality actually exist? His wife, scientist Sophy Valentine, is busy testing her own theory, as well as the limits of science and reality. As a physicist in a neuroscience lab, she’s investigating whether memory has a physical basis in the brain: “Does observation discover the remembered thing, or create it?” Her findings intersect with a classified program built around a brief window of “quantum coherence” in a living brain: “in the picture, blooming hot and red at the boundary where the hippocampus met the cortex—the seam where the brain stitches the present moment into the past—there was the gate.” This “gate” in reality is defined as a Twilight Zone–like gap in which cause and effect fall apart, a phenomenon that Col. Marcus Hargrave, formerly with the Air Force and now in an unnamed, secret position, intends to weaponize. Hope, uniquely sensitive to this gate, is the one person capable of crossing into it. The colonel pressures Sophy with a demand: “Find out why reality is leaking in people.” Hargrave will turn the project into a scientific experiment conducted upon a city and its population—unless the couple can stop his plans.

The premise of Wu’s novel is an addictive, trippy hook. The author displays a skill for conjuring atmosphere: “There is a place in the Nevada desert where the light goes in and does not come out. You can find it on no public map. The road that approaches it is unmarked and ends, eleven miles short, at a fence that the government has not bothered to explain.” Wu’s tight, declarative prose lends an eerie, subterranean flavor to the tale of scientific discovery. The author’s prefatory note about “The scientific framework underlying this novel, including the Inverse Time Dimension Theory,” does little to support the story’s believability, but any concerns about verisimilitude are allayed as the story takes shape. The text has a few irregularities, such as dialogue lines missing question marks (“What do you want.” “May we talk.”), that read as typos rather than stylistic choices, but these are minor blemishes in a compelling narrative that manages to maintain momentum despite the densely packed, science-centered material. While the novel is squarely in the SF realm, it’s the romance and marriage at the story’s center that ground the action and distinguish the book from others in the genre. Wu depicts a relationship worth rooting for as Hope and Sophy stubbornly hold on in the face of threats from external forces and the knowledge weighing them down. A speculative and sharp SF adventure that explores gaps in time and logic.
