I'm not really sure what to make of this book. It's definitely a sci-fi novel, but the emphasis is much more on the "fi" than the "sci". It's also hard for me to glean themes from the book that I remember. The reason I'm giving it 5 stars is simple: it made me feel a lot more than other books do. The stories were simple and poignant, and the writing style was clean and crisp. The characters were relatable, or at the very least easy to sympathize with, and above all, I'm struck by how the key moments in the book are the arguments between the characters. The arguments are what drive the action, and they make me feel... Something. I'm not sure what. Anyway, I really enjoyed this novel, and thought it was very unique in a lot of ways.
