I so loved Nightfall! The first 3/4 of the book were truly brilliant. I was gripped within the first few chapters and couldn't put the book down. The characters were interesting and different, the setting was disgusting and intriguing all at the same time and when people died I felt sad and heart-broken. But at the end of the book I was disappointed and had a few unanswered questions that hopefully will be answered in the next two books! I feel this book deserves a much higher rating than I've given it but the ending really put a downer on Nightfall for me but other than that it was a really great read and would highly recommend.
