Lena, Julian and Alex are now actively involved in the resistance, which brings them back to Portland (well Lena and Alex back, Julian isn't from there). Meanwhile Hana's wedding to Fred Hargrave, t/he dead Mayor's son, has been brought forward due to social pressures. Lena is struggling with her feelings about both Julian and Alex as well as her feelings about her mother, while Hana is struggling to come to terms with her impending marriage and her pair's suspicious past and ex-wife. It all comes to head in a dramatic conclusion...
In a change from the narrative in Delirium and Pandemonium, it is told from the point of views of both Lena and Hana, alternatively. Surprisingly this isn't confusing at all, as they alternate regularly and one of them is cured while the other isn't, though Hana does say more than once that she suspects that her cure did not work properly. Its actually interesting to see the two perspectives side by side, and I think it demonstrates that even if you remove the love from someone they still care about things, you can't escape human nature.
Despite the obvious love triangle, it didn't feel like it was overly pushed. It more felt like Lena was with a boyfriend and is frequently in a room with her ex. But there is the choosing bit at the end, and the thing I liked about the way that the choice wasn't completely given, readers can guess, but Lena did think about the other person in the situation.
The ending itself didn't seem definite, and I liked that, there was no definite resolution. I liked it because it didn't allow things to be miraculously be fine as some books do. Though I would have possibly liked an epilogue showing how things are in 10 to 20 years.
I really liked seeing inside Hana's head, her shocking revelation wasn't that shocking considering that it is heavily hinted at in the ebook novella Hana, but was only confirmed in Requiem. Up until now there has never been much insight into the heads of the cured, or in fact for anyone that is not particularly rebellious. Hana seems to start thinking for herself over the course of the book, especially as she starts to realise what Fred is really like.
Lena grows too, instead of dealing with her problems by ignoring them and carrying on like some protagonists do, she actually thinks about them and acts after thought in a mature manor, it is easy to forget that she is only 18.
One character that I didn't particularly enjoy the characterisation of was Tack. I thought that he was a brilliant character in Pandemonium in the way that he was written, but in Requiem he just seemed to fall a little flat and moved to the background, similarly to Raven, who also seemed to fade into the background a bit.
I enjoyed the book though, it was a good conclusion to the story and didn't let the other two books in the series. Read them!
