The Last Orbit is a science fiction novel that follows a small crew aboard the ISS as they witness the end of the world unfold beneath them. It starts in warmth and routine, with astronauts teasing each other over birthday cake and Bowie songs, and then shifts as they detect what looks like a simple anomaly near the sun. That flicker becomes an approaching asteroid, and soon the crew is watching the Earth fall apart as fragments strike Berlin, Naples, Rio, and eventually the entire Atlantic coast. Cut off from Houston, stranded in orbit, the four astronauts are left with nothing but each other, the damaged station, and the impossible weight of survival in a world that no longer exists below.

The writing is simple and vivid, almost cinematic, but what pulled me in most was the emotional pacing. Author Mark Heathcote lingers on quiet moments: a tomato drifting in a hydroponic bay, a Polaroid stuck to a wall, the metallic creaks of the station as it flexes in shadow. These details make the early chapters feel warm and lived in, which makes the later horror hit harder. When the asteroid fragments start landing, the scenes are brutal, shown through the detached silence of orbit. That contrast makes everything sharper. I kept thinking how strange it is that a catastrophe can look almost beautiful from far away. The author plays with that feeling a lot, letting awe and dread sit side by side.

What I enjoyed most was how grounded the characters felt. Their reactions aren’t heroic or polished. Sometimes they panic. Sometimes they shut down. Sometimes they argue because there’s nothing left to do and nowhere left to go. I appreciated that the author didn’t try to tidy their emotions. Ava’s insistence on discipline, Greg’s grief-strained anger, Koji’s quiet resilience, Lena’s obsession with data as a kind of ritual. None of it feels dramatic for drama’s sake. It feels like people are trying to hold on to something solid when the world below them is literally being torn apart. The book leans into the psychological weight of isolation rather than into action-heavy sci-fi, and that choice makes the story feel more intimate.

The book is bleak, yes, but also reflective, in a way that reminds me of standing outside on a cold night and realizing how small you are. If you like science fiction that mixes disaster with character-driven storytelling, or if you enjoy space settings that feel tactile and real instead of glossy, this book will be right up your alley. Readers who appreciate slow-building tension, emotional honesty, and apocalyptic fiction seen through a very human lens will get the most out of it.
