If you were hooked by Hester Marley's step‑by‑step sleuthing through airtight corridors and sealed cabins, you'll love how The Spare Man strands celebrity engineer Tesla Crane on a luxury starliner where a body drops and suspects are everywhere. The banter is sharp, the clues are fair, and the shipboard procedures—security sweeps, access logs, passenger alibis—scratch the same investigative itch as Hester piecing together a murder in deep space.

Did the ruthless megacorp politics behind Hester's contract and the way a single murder exposed rot at the top hit home? In Company Town, bodyguard Hwa takes a job protecting the heir to the family that owns an entire offshore city—then a killer starts staging murders like a ticking message. The labor tension, privatized justice, and boardroom stakes echo the corporate maze Hester navigates, but with a gritty, street‑level immediacy.

If you admired how Hester Marley keeps her head—smart, stubborn, and resourceful—while unraveling a conspiracy in the Belt, meet salvage pilot Haimey Dz. In Ancestral Night, a derelict find turns into a galaxy‑spanning secret, and Haimey has to outthink pirates, cops, and her own past. Her partnership with the ship AI Singer and her moral calculus under pressure should resonate with Hester’s blend of grit and heart.

If what gripped you was being inside Hester's head as isolation, fear, and doubt crept in while she worked a deadly problem in tight quarters, The Luminous Dead delivers that intensity in spades. Caver Gyre Price descends into an alien cave system with only her remote handler, Em, in her ear—and lies, manipulation, and obsession turn the mission into a mind game. It’s the same intimate pressure cooker and unraveling psyche that made Hester’s investigation so compulsive.

If you liked how Dead Space kept the stakes tight—one ship, one crew, one murder—and let procedure, logs, and gut instinct drive the reveals, meet Murderbot. In All Systems Red, a survey mission goes sideways when a contractor cuts corners and people start dying, leaving a single security unit to investigate and protect the team. The contained setting, corporate malfeasance, and methodical problem‑solving mirror Hester’s claustrophobic, boots‑on‑the‑deck detective work.
