 This is a really difficult review to write. The Delirium trilogy has meant a lot of me and I'm sad to see it come to a close. I still remember when I first picked up Delirium on a whim, during a Borders closing sale. I had no idea what the book was about or who Lauren Oliver was - I only knew I had seen the cover on some blogs and people seemed pretty excited for it. I had no idea I was picking up what was soon to become one of my favourite books and that Lauren Oliver was about to become an author I would never forget. 
 I had a lot of expectations going into Requiem. And a lot of fears too. Would the series end the way I wanted it to? Would my heart end up smashed into a million pieces? It was a lot of pressure for one little book. 
 There's really not much I can tell you about the plot of Requiem without giving anything away. I will say that there was a certain direction I thought this book would go in and it didn't. But that isn't a bad thing. I like the direction Lauren Oliver chose to take series in. It was different and unexpected and because of that it kept me guessing. It wasn't what I expected but that worked out for the best because that meant I was just as obsessed with finding out what happened next as I had been in Delirium and Pandemonium. 
 The unique thing about Requiem was the addition of alternating chapters between Lena and Hana's point-of-view. I have to say I really enjoyed Hana's chapters. Having read the short story, Hana, I found I wanted to know more about her character and what she had been up to. But even if you haven't read the story, you're going to be heavily invested in her chapters. There is some crazy stuff in there! And as always I enjoyed Lena's voice. I think she's grown a lot over the series but she's still not perfect - which in my opinion is how it should be. She's still so young and has so much ahead of her, it would be crazy for her to have it all figured out. 
 However, I do have one criticism of Requiem. It doesn't change my overall feeling about the novel/series but it did leave me a little disappointed. I found there are certain issues that don't get addressed until late in the book. And because they are presented so late they really don't get as fleshed out as I would have liked. There are two in particular that kind of bugged me and left me wanting more. I think there was so much potential to explore the effects of certain relationships and it just wasn't met. I know I'm being super vague but I don't want to give anything away. If you've read the book I'd love to hear your thoughts on it. Perhaps a discussion post is in order? 
 Reservation aside, I do think Requiem is a beautiful end to an amazing series. Lauren Oliver has brought to life some amazing characters, she has made me cry sob, kept me up until all hours of the night, eyes glued to the page. She has given me a series that I want to re-read over and over. The Delirium series is a powerful story of love and resistance and freedom with universal themes everyone can relate to. So this isn't so much a review as it is a love letter to Lauren Oliver. <3 
 Recommendation: A hard breaking but strong end to a fabulous series. A must read.
