Convincing plot, interesting thoughts, okay characters, lazy worldbuilding. Which makes sense, I suppose, because the author clearly wanted to write philosophical speculative fiction (which they succeeded in), not focus delving into a complex backstory and world far enough to make readers understand it. Unfortunately that also made other thoughts the book discusses more simplistic and flat than they could have been.

As other reviewers have said, this book was mismarketed, but only insofar as it isn't mainly a romance. It's definitely YA, for inquisitive young readers who like to dig deep into philosophical questions.
