I have a significant number of horror recommendations, but recently read a very good one. Dead Silence by S.A. Barnes.
Its about a small maintenance crew out in space discovering a luxury cruiser that had gone missing a decade ago, taking with it all its extremely wealthy occupants. The crew decides rather than report it in they will take control of the ship and fly it back to mapped space. Naturally what caused the ship to go missing is still waiting for them.
The setting is 10/10, the mystery kept me guessing (genuinely did not know if the scary things happening were supernatural or sci fi in origin for most of the book)
And it gets bonus points for handling mental health well. The narrator has been seeing hallucinations since she was a child. And while most horror stories would make the schizophrenic part of the tension. Her history and years of therapy meant she was better at telling whats real and whats her mind being messed with so she managed to push through most of the ghostly things.
