strings between the stars by writevale
The Magnus Institute is an astronautical vessel tasked with the mission of locating and investigating a string of previously untouched planets for potential human habitation. Led by a newly replaced computer system, The Archivist 2.0, the crew are woken up from centuries of sleep to research a new planetoid-mass. But will Archival Assistant Martin Blackwood and the other crew members find more questions than answers on the planet's surface? And why does the computer's voice make him feel like that?

lots of cw, but the author’s great about listing them at the beginning of each chapter, so I’ll leave this one to them. It’s mostly just canon-typical body horror, and in chapter five, some sex-adjacent incidents.
