BEFORE MARS by Emma Newman

A new review over at Tor.com:

Before Mars is the third novel in Emma Newman’s Planetfall universe, loosely connected to its predecessors, 2015’s Planetfall and 2016’s After Atlas. Readers of After Atlas will come to Before Mars with some foreboding: we already know that the creeping sense of horror Before Mars protagonist experiences will have to pay off, one way or another—especially as it becomes clearer how the timeline in Before Mars lines up with that of After Atlas.
