It’s incredible that a work of speculative fiction first outlined over a decade ago would require a content warning in its review. But it must be said that the subject matter of Sequoia Nagamatsu’s ambitious debut, an elegiac collection of interconnected stories centering on a global plague that decimates humanity, is particularly challenging in our current climate.
Beginning with a group of explorers who unwittingly unleash a mysterious virus that had long lain dormant beneath Siberian ice, How High We Go in the Dark chronicles humanity’s battle against the “Arctic plague” in the following decades and the ways in which society adapts and changes. Each chapter moves forward in time and features a different protagonist, giving readers the chance to inhabit multiple lives, realities and perspectives over the course of the narrative.
Among the varied cast of characters are a worker at a euthanasia theme park for terminally ill children; a scientist who, while cultivating organs for human transplant, unintentionally creates a talking pig; a physicist who gives humanity a second chance at life by opening a stable wormhole in his head, which will allow for interstellar space travel; and the eventual crew that leaves Earth to search for a new planet to colonize.
Early chapters feel self-contained, but as the novel progresses, it is satisfying to observe the ways the sections interconnect with and amplify one another. When the full scale of Nagamatsu’s vision comes into focus in the final chapter, the narrative resonance on display is thrilling in a manner reminiscent of David Mitchell’s mind-bending masterpiece, Cloud Atlas.
Still, despite the fantastical elements woven throughout, there is no real way of escaping or softening the novel’s inherently bleak and brutal reality, in which death, loss, trauma and grief are at the forefront. And while Nagamatsu explores resilience, love and our primal need for connection, there’s no denying that the process is a sad one. Any glimpses of hope are generally fleeting and bittersweet.
It’s unfair to penalize a book for being too relevant and ringing too true, but for readers who turn to fiction as a means of escaping the stress and worries of real life, How High We Go in the Dark might be best saved for a later date. However, those courageous enough to sit with the novel’s exquisite sorrows will be rewarded with gorgeous prose, memorable characters and, ultimately, catharsis.
