Planetfall, Emma Newman. This has been on my list almost as long as Rosewater, since slightly later in 2017, so another thank-you to the Hugo Series ballot for scooping up some of these slightly-older works that get lost in the rush of trying to keep up with new releases. All comments behind cut.

Unfortunately I found this book frustrating. On paper, it sounds like there's a lot of good stuff going on here: a little 2001, a little Contact, a little Rendezvous with Rama, a little Semiosis. But in practice it was more of a "maybe humans are not worthy of space" tragedy, with this whole expedition coming within, like, a literal hundred yards of world-changing discoveries, but failing due to lies and power-hunger and shit like that. And then also the POV character turns out to be reacting to her PTSD with compulsive hoarding. Which on the one hand was interesting in the SFnal context of print-anything-on-demand tech, and also I'm not sure I've ever seen a story quite like that, "what happens when we bring our real Earth mental illnesses to space with us", and on the other hand was deeply uncomfortable to read. I could see it being powerful if this was ultimately a story of healing and recovery, but as it was it just felt like a way to torture the protagonist (and by extension, the audience). Her ultimate escape from the disaster of the plot into some kind of alien transcendence felt both unearned and unsatisfying. I do not plan to read further in this series.

ETA: I'm amused that this book apparently got blurbed by Seanan McGuire and has in common with McGuire's writing a determined focus on some part of the story I find less interesting, away from all the most compelling elements. So maybe if you like McGuire this will also work for you. :)

ETA 2: I suppose I should give it credit for being queer. But "queer characters of color get to die tragically in space" just doesn't satisfy any reading desire I have right now. I mean, yes, queer characters of color should get to occupy all the possible roles! But right now (and, to be honest, probably all the time) I want to read about such characters *triumphing*, and living long blissful lives with their partners, and stuff like that. (Genre-romance HEAs still looking reeeeal good, sigh.)
