I’ve had this book on my shelf for a while, and I’m glad I finally picked it up. The description makes it sound like cli-fi, but really, it was a story about trauma, found family, facing demons and finding peace.
At first I was disappointed, because I like literary sci-fi, and was hoping for something more creative and atmospheric. But, the emotional lyricism grabbed me, as did the plot as it became clear Franny was keeping some rather heavy and dangerous secrets.
McConaghy’s use of a narrative device, that is often employed in novels to divert the reader, seemed evident (I’m not going to disclose it, because it would spoil the book - but IYKYK.) This might be offputting for some readers, but I think she used it in a way that worked well with the character development.
Though I had my guesses about the other secrets, they all went in directions I did not see coming. I was especially glad that the ending didn’t go how I had expected. 
All very vague, I know. This slim, but impactful, volume is worth checking out and learning the secrets within!

“He said our lives mean nothing except as a cycle of regeneration, that we are incomprehensibly brief sparks, just as the animals are, that we are no more important than they are, no more worthy of life than any living creature. That in our self-JJ importance, in our search for meaning, we have forgotten how to share the planet that gave us life.”
