My thanks go to Net Galley and Flatiron Books for the review copy. I alternated my digital copy with the audio version I found at Seattle Bibliocommons; the reader does a fine job, and so if you want this book, you can’t go wrong in terms of print versus sound.

This is either exactly the right time to read this book, or exactly the wrong time.

Franny Stone has never been happy staying in one place, and now, when the walls are about to close in on her, she decides that one final voyage is in order. The Artic terns are about to make one final migration, and she means to go with them. Posing as a marine biologist, she persuades a fishing crew to take her along; she has the data to follow the terns, and the terns are following the fish. It’s in everyone’s best interest to work together here, now that so many species are extinct and the fish are so scarce. Once in motion, however, few things go according to plan.

The setting is the future, at a time when humanity has depleted most of the world’s wildlife. It is bleak, bleak, bleak.

Much of the story revolves around Franny’s character, and since we know from the get-go that she doesn’t intend to return alive once this trip is done, there are two questions that keep me turning the pages. I want to know why she wants to die, and of course, whether she does. The reason for her morbid plans is spooled out to us in small bits; whether she dies at the end is something the reader must learn for herself.

As for me, I had huge expectations by the time I began reading, because this novel shot up to bestseller level almost overnight. Perhaps that’s why I felt a trifle let down when it was done. It’s a good story, but I wouldn’t call it one of the year’s finest. Certainly, there is moral gravitas behind it, and yet those most likely to read it are not climate change deniers. For me to have loved this story, I would have needed more hope and less utter despair. When a story starts sad and ends sad, the little places in which it is slightly less sad aren’t enough to bond me to the narrative.

On the other hand, I am just one reviewer. There are a whole lot of readers out there getting all the feels and loving them. I recommend this story to anyone looking for a catalyst for a good ugly cry.
