Based on the description, the book is supposed to be a post-apocalyptic science fiction novel. It reminded me more a historical one. Though there is a precedent for this type of story with the Revolution TV series.
What happens if the world you live in isn’t the one you belong in? That’s the dilemma that Charlie Blake faces. The book reminded me of Lord of the Rings because of it storytelling style and the amount of characters I was exposed to.
