In short: I was disappointed with the lack of closure in Requiem by Lauren Oliver, but I did like it overall. 
 It was with a bit of nervousness that I entered into Requiem, knowing that it had had some mixed reviews and people especially seemed to have a problem with the ending. I absolutely LOVED Delirium when it was released and was completely blown away by Lauren Oliver's gorgeous prose. Its sequel, Pandemonium, was pretty good, though I felt that the story had lost a bit of the magic that had kept me enthused about the characters and the plot in Delirium. For me, Requiem falls a bit below Pandemonium in ratings - not a terrible read and pretty exciting in parts, but in other ways, it was pretty disappointing. 
 For me, one of the most important factors in evaluating the overall satisfaction of the final book in a series is whether the major questions were answered and whether most loose ends are tied up by the series' close. On this point, Requiem kind of fails for me and I'm sorry to say that I agree with the majority reader opinion in not liking the ending as it stands. Some people may like the open-ended ending, as it allows them to form their own conclusions about the future of the characters and plot, but for me, I needed more resolution, especially for the love triangle. Where was my closure? I feel like we are owed that for sticking with the series to the end. Unnecessary epilogues annoy me, but I feel like this is one case where I really would have liked to have seen one. 
 And I'm sorry to say I wasn't in love with Lena's character in Requiem. I liked her quite courage and wilfulness in Delirium and I really loved her growth to a strong, mature person in Pandemonium, but I feel like she regressed a bit with two boys in the picture in Requiem. I really hate that she was stringing along one of the boys while actually liking the other one more. Oh, love triangles - why must you make assholes out of people? I didn't have any particular preference for either of the boys going into Requiem, but that doesn't mean that I didn't experience dissatisfaction with the outcome due to Lena's handling of the situation. 
 I don't mean to be so hard on Requiem because I did like it overall. I liked the action scenes and I liked the inclusion of Lena's ex-bestie Hana's point of view into the story as it provided an opposing viewpoint of the resistance. There were just the few faults outlined above that I found couldn't get past. Still, it is always such a treat for me to get to experience Lauren Oliver's writing. I have yet to be disappointed by it and count myself as a life long fan. Middle Grade, Young Adult, Adult - I will read whatever she has planned and am guaranteed to be blown away by her writing skills.
