REQUIEM is told from Lena and Hana's point of view. Being former best friends, the pair now have totally different lives. Hana was cured and now struggles with the aftereffects of the procedure. Lena is an Invalid or Uncured and has fled to the wilds.

Groups of rebellions have opened up throughout the country. The number of the Invalids or uncured is rising. The government can no longer deny that they exist. Therefore, Regulators have been dispatched to the wilds to destroy any and all they come in contact with.

Lena and her friends have fled to the wilds. Lena feels as if she is being pulled in two different directions. She has finally found Alex alive....but now that she has helped free Julian from the crypts and shared a kiss with him, her feelings are all over the place.

Back in Portland, Hana Tate, Lena's cured former best friend, lives a safe and loveless life. She is paired with Fred Hargrove, who is the new mayor of Portland. Hana sees her former life slowly slipping away from her. She assumed the cure would end all feeling. But her guilt of betraying Lena an Alex are still there.

When Hana is whisked away from the Labs when it is attacked, she literally runs into Lena. The two girls are surprised to see one another. Hana allows Lena to escape after telling her the source of her guilt. Lena warns her of the bomb that is planted in the house she is now sharing as wife of the Mayor.

As third book of the Delirium series, if you haven't already done so, I recommend reading the first two novels before this one. I could easily follow the plot, but the history up to this point in the series was lost to me as well as the history between characters. There is some back-story with this book, just not enough to really understand the characters. For me there was no real ending...no explanation of what happened or if anything was resolved in the end, and I was left anticipating the next book in the series.
