My emotional states fluctuated a lot while reading this book. Because of the romance aspect in this book and the characters. I didn't like Harlan or Noys, the stereotypical woman character. But, I persevered, since the sci-fi aspect of the novel was well-written and thrilling. Even though I felt unwillingness to finish the book, until I saw Cooper's twist, thus I continue to read. At first glance, the character Noys seemed like a tool to sustain the story and give a reason to Harlan. But at the final, everything has changed. Noys had moral and reason, thus Noys becomes a real character, not just a tool. The final twist got me and the change of the character Noys and my whole opinion on this book.
