This is what was once called speculative fiction, a sort of thought provoking sci-fi or dystopia.
There's a dystopia background and there's a lot about memories, living, and surviving.
The author did an excellent job in making me feel the emotions of the characters including the claustrophobia and nostalgia of past experiences.
Great storytelling, plot and character development.
Highly recommended.
Many thanks to the publisher for this arc, all opinions are mine
