Title: The Upper World
Author: Femi Fadugba
Format: eBook
Genre(s): Science Fiction, Young Adult
Rating: ★★★☆☆
This is a unique piece of young adult science fiction, melding real physics, time travel, and two main characters from southeast London. It tells the story of Esso, a high school boy who has an accident that gives him a glimpse of a place out of time, and Rhia, a girl who grew up in foster care and is searching for more of her history.
I had a great time learning more about the physics woven into the story and ended up having numerous conversations about the theory of relativity as a result. The point where the physics meets the time travel was (understandably) a bit vague and hand-wavy, and there’s a simplicity to the story that I associate with young adult fiction — neither of which are necessarily a problem, if that’s your cup of tea. The book does a fantastic job jumping between Esso and Rhia’s storylines, building up the conflict and drama to an exciting climax and satisfying conclusion.
