5 Non-Sci-Fi Books to Read After Project Hail Mary

Andy Weir’s “Project Hail Mary” has leapt from page to screen with remarkable force. The novel, first published in 2021, quickly earned a Hugo Award finalist nod and held a place on the New York Times best-sellers list for more than a year. Its 2026 film adaptation, directed by Phil Lord and Chris Miller, has become one of the year’s biggest cinematic success stories, anchored by Ryan Gosling’s turn as amnesiac astronaut Ryland Grace and James Ortiz’s motion-capture performance as the eyeless, sound-wielding Eridian named Rocky.

For readers who loved the novel, the movie, or both, the appetite for stories with similar emotional DNA often runs deeper than the sci-fi shelf. Themes of survival, unlikely cross-species friendship, identity excavation, and high-stakes problem-solving all thread through the narrative. Fortunately, those same motifs echo across centuries of literature that has nothing to do with interstellar travel.

The Project Hail Mary Phenomenon

Before exploring the recommended reading list, it helps to understand why Weir’s work has struck such a chord. “Project Hail Mary” follows Grace, a former science teacher thrust into a desperate mission to save Earth from extinction, who wakes aboard a spacecraft with no memory of how he got there. His gradual recovery of identity is interwoven with his growing bond with Rocky, an alien engineer whose species perceives the universe entirely through sound. Together, the two must bridge profound biological and cultural divides to crack a problem that could determine the fate of two civilizations.

That combination of scientific problem-solving, deep emotional stakes, and a friendship that transcends species is rare. Readers drawn to those elements may be surprised to find echoes of them in books as varied as a 1719 shipwreck narrative, an Irish novella about conscience, a Japanese cat story, an underwater thriller, and a collection of essays by one of the most famous figures in disability history.

A Classic Survival Tale: Robinson Crusoe

Daniel Defoe’s “Robinson Crusoe,” published in 1719, remains one of literature’s foundational survival stories. The novel follows its title character through a series of ill-fated sea voyages that culminate in a shipwreck on a remote uncharted island off the coast of Venezuela. Cut off from society, Robinson must rely on salvaged materials from his wrecked ship to build shelter, cultivate food, and endure nearly three decades of isolation.

Where the book diverges from a simple castaway tale is in the arrival of Friday, a captive Robinson rescues from itinerant marauders. The two men navigate language barriers, build trust, and eventually collaborate on ambitious projects, including the construction of boats and the liberation of additional prisoners. Their evolving relationship, despite the novel’s dated colonialist framing, can be read as a meditation on cross-cultural exchange. For readers who connected with Grace and Rocky’s patient, creative attempts to communicate across species lines, “Robinson Crusoe” offers an earlier, earthbound echo of that dynamic.

Identity and Conscience: Small Things Like These

Claire Keegan’s “Small Things Like These” shares “Project Hail Mary“‘s preoccupation with a protagonist forced to revisit his own past in order to do the right thing. The novella centers on Bill Furlong, a taciturn middle-aged Irish coal and fuel merchant raising his family during Margaret Thatcher’s premiership in the 1980s. Bill’s quiet routine is disrupted when he encounters a young woman at a facility marketed as a Catholic training school, but which functions as one of Ireland’s notorious Magdalene laundries, where “difficult” women were effectively enslaved.

Keegan’s spare prose brings both the small-town religious backdrop of 1980s Ireland and Bill’s suppressed childhood memories to vivid life. Confronting those memories reshapes his sense of self and, ultimately, his willingness to act. As with Grace’s journey, the discovery is uncomfortable but transformative. The book has been adapted into a well-received film starring Cillian Murphy, giving readers an obvious follow-up screening after finishing Keegan’s short, powerful text.

Bonds Across Species: The Travelling Cat Chronicles

Hiro Arikawa’s “The Travelling Cat Chronicles” reframes the question of cross-species connection by centering it on the cat Nana and his owner Satoru. The pair travel across Japan, visiting old friends from Satoru’s youth over the course of a year. The stated purpose of the trip remains oblique for much of the narrative, and Arikawa treats that ambiguity as a feature rather than a flaw, letting the journey itself carry the emotional weight.

Like Weir’s novel, the book uses flashbacks to weave characters’ pasts into the unfolding present, demonstrating how earlier choices reverberate into current circumstances. Arikawa’s central insight is that our animal companions often perceive us with a clarity and acceptance that human relationships cannot match. Nana’s vantage point, observing his beloved human with gentle, uncritical affection, parallels Rocky’s perspective on Grace in its own quiet way. For cat lovers in particular, the novel offers a meditative look at love, loss, and the strange comfort of being truly seen by another creature.

Survival on Earth: Whalefall

If “The Martian” is the obvious Andy Weir follow-up, Daniel Kraus’ “Whalefall” is its wildly inventive cousin. The premise is exactly as strange as it sounds: a young diver searching for the remains of his father is accidentally swallowed by a sperm whale, and must escape using every tool and every ounce of willpower at his disposal before his oxygen runs out.

Kraus, who recently won the Pulitzer Prize for his dark fantasy novel “Angel Down,” treats the absurd high concept with the same technical rigor Weir brings to space-bound survival. The result is a tightly wound, real-time thriller that uses flashbacks to deepen the stakes rather than slow them down. A film adaptation of “Whalefall” has been discussed, with observers curious to see how such a contained, claustrophobic story will translate to the screen. Readers who want the problem-solving intensity of “Project Hail Mary” without leaving Earth’s atmosphere will find it here in concentrated, adrenaline-soaked form.

Seeing Differently: The World I Live In

The most distinctive element of “Project Hail Mary” may be Rocky’s radically different mode of perception. Born without eyes, the Eridian navigates his environment through sound waves, perceiving solid objects through walls while remaining oblivious to the visual beauty of his own planet. For human readers accustomed to sight as the dominant sense, this inversion is one of the novel’s most disorienting pleasures.

Helen Keller’s “The World I Live In” offers a real-world parallel. A collection of essays in which Keller, who lost both sight and hearing in infancy, describes how her remaining senses of touch, taste, and smell gave her a vivid and even expansive awareness of the world around her. Her prose is poetic and sensory, treating vibration and texture as forms of sight in their own right. She writes, “Sometimes, it seems as if the very substance of my flesh were so many eyes looking out at will upon a world new created every day,” and later describes her body as “a vibroscope” attuned to the rhythms of the air.

For anyone curious about what it might actually feel like to inhabit Rocky’s perceptual world, Keller’s essays are an unexpectedly direct match. The book has been in print in various editions for more than a century and remains widely accessible through libraries and digital retailers.

A Reader’s Takeaway

What unites these five very different books is the same quality that makes “Project Hail Mary” resonate: each one takes the inner experience of its protagonist seriously, even when that experience is radically unlike our own. Defoe’s castaway, Keegan’s coal merchant, Arikawa’s cat, Kraus’s trapped diver, and Keller’s deafblind essayist all invite readers to inhabit unfamiliar perspectives while grappling with familiar questions about identity, memory, friendship, and what we owe to one another.

Readers finishing Weir’s novel in any of its forms, print, audiobook, or the Lord and Miller film, have a rich set of follow-up journeys waiting. Some are short, some are long, some are centuries old, and some are contemporary bestsellers, but all reward the same kind of patient, attentive reading that “Project Hail Mary” demands.
