A strong So-So, marked down due to my personal preference rather than the quality of the book. Because this is a really good novel with a lot of really good stuff to unpack. The backdrop is a world devastated by risen sea-levels but it's not a cli-fi novel. It's about relationships & it has a low-key intensity that is poignant & thought provoking. There's a subtle, one line twist that throws the whole thing into a new light which I appreciated.
