A very emotionally powerful book. I enjoyed the first half more than the second half, as the story devolved increasingly into quite melodramatic and difficult to believe plotpoints.

The crew becoming so ride-or-die for Franny? Ennis and Franny managing to walk across fricking Antarctica with no prep and barely enough food, yet surviving? Also how did they get back afterwards? How did the ships survive such long journeys when they were breaking down? I don't mind suspending disbelief but I felt like my suspension was doing some seriously heavy lifting.

 
Nevertheless, the themes and characters were powerful enough that it affected me emotionally, even if from a plot point of view I was dubious.
I read McConaghy's second novel about wolves first, and I've got to say they are remarkably similar - it feels a bit like she copy and pasted the template, but I guess if it works it works. But like her other novel, it's billed to be about climate change and wildlife destructions but deviates a lot from that plot/theme to explore the character's own trauma. That isn't a problem per se, but the birds and climate change plot felt a little unfinished, like it petered out because she didn't exactly know where to take it. BUT, not nearly as much as in the wolves book, hence my higher rating for this one. The near apocalyptic world also felt somewhat underdeveloped (if that much wildlife had died off, humanity would be struggling a lot more). 
On the writing, it was very evocative and emotionally powerful. And that's when I'm reading it in Swedish, which isn't my native language - if the emotion and skill in describing the natural world and bodily experiences survived that much level of translation, I reckon if I'd read it in the original English this writing would have hit me like a truck and left me a blubbering mess on multiple occasions. As it was, I just cried at the end (on a public bus!).
Important to be aware that it's a lot darker than the blurb would imply so definitely heed the content warnings - of which there are many and very explicit. There's no option for ecocide in the content warnings, but like big time on that (of course).
Overall, I did... Enjoy isn't the right word, but I was transported by this book. I learnt about birds, and it's left me thinking a lot about how I want to treat the people - human and animals - in my life, and perhaps that's the most important thing of all.

Ein fantastisches Buch mit sehr viel Tiefe, vor allem in den Charakteren. Die Botschaft des Buches ist ebenfalls eine sehr wichtige; wie würde eine Welt aussehen, in der es keine Wildtiere mehr gibt? 

Von mir eine klare Leseempfehlung, auch wenn ich nachvollziehe kann, wenn es evtl. dem Einzelnen, zu "Düster" ist.

I loved this- a thoughtful book that feels dystopian yet not far from what’s possible in the near future. The characters were believable and heartbreaking. A perfect combination of a well thought out future world and interesting main character plot. 

This was a bummer all around but interesting story line. 

I don't have words for this book. It's so masterfully written and so incredibly sad. I hope this devastating world doesn't come to pass.
