Lauren Oliver’s Delirium is set in an unidentified American future in which the "disease" of love has been cured. Lena is set to have her cure in a few months, and the book follows her from her evaluation – to determine her future partner and schooling – through the summer to right before her cure. In this time Lena finds out that a number of things she has been taught over her life are lies, and that there are more important things than being cured and being "happy."

We are also introduced to Lena’s family, her friend Hana, and Alex, a worker at the center that cures everyone, who has his own secrets.

There are a number of beautiful moments in the book, the descriptions of the scenery around Portland, Maine, is especially well described. There are also a number of dark scenes surrounding the officials who keep everyone in line until they are cured, and the security the government goes to to keep everyone happy and to keep rebels out of the system.

The book is reminiscent in many ways of 1984 by Orwell and the Uglies books by Westerfeld, but has enough of its own unique story to keep it fresh and new. Oliver’s writing style is different and keeps the pace of the story moving right until the end. Delirium is the first of a series and the ending definitely keeps you wanting more. It would be a good read for anyone high school aged or older.
