Honourable mention: Requiem For A Mouse by Miranda James
Murders have a way of happening in the vicinity of Mallory Viridian, so she leaves Earth for an alien space station, Station Eternity, where there are only two other humans and she keeps contact with them to a minimum. But now a group of VIPs and tourists from Earth has been allowed to come to visit.
Interesting world building and aliens & an intriguing mystery. I'm not quite sure how the story can continue so I'm diving straight into the sequel.
