I just finished Red Rising, and oh gods it's so good! 4.5/5 stars. I'm so glad that, because of all the recommendations in FF, I decided to go through with it, despite having DNF'd the book around the first few pages twice before now. The worldbuilding of all the colored races are interesting as hell, and this book had so much twists and turns that every few chapters it'd take off in a direction I'd never expect it to go before. I just can't wait for the second book to arrive already, urgh!
