Seveneves by Neal Stephenson

Imagine the Moon shattering overnight, sending humanity scrambling for survival in orbit. That’s the epic premise here. Stephenson takes you through incredible technical challenges, like constructing habitats in space and sustaining human life, spanning generations. While it’s massive in scale, it shares that nail-biting tension and clever thinking you loved in Project Hail Mary. Plus, the way he explains orbital physics and survival logistics is fascinating, like getting a crash course in real science disguised as a thriller.
Leviathan Wakes by James S.A. Corey (The Expanse 1)

If you’re into space adventure with political intrigue, alien mysteries, and a crew that feels like friends, this one’s a gem. The story kicks off with a missing person case that turns into a solar-system-wide crisis. Corey mixes technical space details with deep character work, giving you tension, surprises, and clever solutions to impossible situations. It’s got the same “how on Earth -or Mars- do they fix this?” feeling as Ryland Grace’s adventures.
Artemis by Andy Weir

If you loved Weir’s wit in Project Hail Mary, Jazz Bashara is a joy. She’s a smuggler and troublemaker in the Moon’s only city, constantly getting into sticky situations that she solves with brains, cunning, and a touch of rebellion. The story mixes humor, thrilling heist scenarios, and scientific plausibility, giving you the same clever problem-solving vibe without the life-or-death survival on a distant planet, but still plenty of stakes and fun.
Old Man’s War by John Scalzi

This one’s equal parts funny, thrilling, and thought-provoking. Imagine seniors getting the chance to swap into enhanced soldiers to fight an interstellar war. John Perry, our protagonist, is charming, witty, and instantly relatable. The novel blends clever futuristic technology with questions about morality, war, and what it means to survive in extreme circumstances. It’s like a buddy-comedy meets hard sci-fi in space.
The Three-Body Problem by Liu Cixin

This is a cerebral, mind-bending story about humanity’s first contact with an alien civilization. The book dives deep into physics, astronomy, and even philosophy while keeping the tension high. The narrative spans decades and cultures, presenting a slow-building suspense as humans confront technology far beyond their understanding. If you loved the intelligent alien problem-solving in Project Hail Mary, this one will challenge and thrill you in equal measure.
Dark Matter by Blake Crouch

If you’re in the mood for a reality-twisting adventure, Dark Matter is perfect. Jason Dessen’s life flips upside down when he’s pulled into alternate versions of reality, forcing him to confront not only survival but identity and choices. It’s fast-paced, clever, and emotional, blending theoretical physics with human vulnerability. The stakes are huge, and the science-driven tension mirrors the high-pressure problem-solving you enjoyed in Weir’s work. Don’t forget to check books similar to Dark Matter!
Children of Time by Adrian Tchaikovsky

Here’s a brilliantly imaginative one: humanity tries to colonize a planet, but evolution takes an unexpected turn, and intelligent spiders rise. The story balances science, philosophy, and thrilling survival challenges, following both the evolving species and the remnants of humanity. It’s epic, inventive, and deeply satisfying for anyone who loves clever solutions to extreme problems, just like Ryland Grace figuring out alien biology.
The Bobiverse Series by Dennis E. Taylor

This is fun, funny, and deeply imaginative. Bob wakes up as an AI tasked with exploring the galaxy, and his adventures mix science, humor, and existential reflection. From terraforming planets to communicating with alien civilizations, each problem Bob faces requires clever thinking, humor, and persistence. It’s a lighter, heartwarming take on space exploration that still scratches the “science-driven ingenuity” itch perfectly. You should give it a chance if you’re looking for books similar to Project Hail Mary.
Columbus Day by Craig Alanson

If you want action with a smile, this is it. An average guy is suddenly humanity’s ambassador to aliens, thrown into chaos that tests his cleverness and courage. It’s fast, witty, and full of inventive solutions, with a style that’s like Project Hail Mary meets a sci-fi buddy-comedy. The humor keeps it light while the stakes keep it gripping.
Foundation by Isaac Asimov

The classic saga of psychohistory, planning, and human ingenuity across a collapsing galactic empire. While not about lone survival, the meticulous strategies, clever foresight, and problem-solving echo the cerebral thrills of Project Hail Mary. It’s a must-read if you enjoy seeing intellect and planning navigate impossible odds.
Rendezvous with Rama by Arthur C. Clarke

Classic sci-fi at its finest. A massive alien spacecraft enters our solar system, and humans explore it meticulously. Clarke captures that awe-inspiring feeling of first contact with the unknown. There’s tension, curiosity, and clever problem-solving as humans try to understand something utterly alien. If the scientific wonder of Ryland Grace exploring strange phenomena appealed to you, this will give you that same thrill in spades.
The Forever War by Joe Haldeman

This one is equal parts military sci-fi and philosophical reflection. William Mandella fights an interstellar war, but time dilation means Earth keeps changing around him. It’s heartbreaking, thrilling, and full of moments where strategy and survival intersect. It shares Project Hail Mary’s sense of problem-solving under pressure, but adds a layer of social commentary and emotional depth.
Altered Carbon by Richard K. Morgan

Dark, thrilling, and packed with mystery, this book explores a future where consciousness can move between bodies. It’s more noir than hard sci-fi, but it’s full of clever technological solutions, strategic thinking, and survival in a high-stakes world. If you liked the tension and problem-solving in Project Hail Mary, this one scratches a similar itch with a grittier, futuristic twist.
The Calculating Stars by Mary Robinette Kowal
