Delirium Trilogy

First book in the DELIRIUM Series 
Before scientists found the cure, people thought love was a good thing. They didn’t understand that once love -the deliria- blooms in your blood, there is no escaping its hold. Things are different now. Scientists are able to eradicate love, and the governments demands that all citizens receive the cure upon turning eighteen. Lena Holoway has always looked forward to the day when she’ll be cured. A life without love is a life without pain: safe, measured, predictable, and happy.

But with ninety-five days left until her treatment, Lena does the unthinkable: She falls in love. 
Delirium is Lauren Oliver's second book, and also, the first in the Delirium Series. It was published on February 1st, 2011 by HarperTeen.

Second book in the DELIRIUM series
I’m pushing aside the memory of my nightmare,
pushing aside thoughts of Alex,
pushing aside thoughts of Hana and my old school,
like Raven taught me to do.
The old life is dead.
But the old Lena is dead too.
I buried her.
I left her beyond a fence,
behind a wall of smoke and flame.
Lauren Oliver captivated readers with Delirium, the first book in a thrilling dystopian trilogy in which Lena Haloway dared to fall in love with Alex and escape the cure, the government-mandated procedure that renders a person immune to the disease of love. Lena and Alex staked their lives on leaving their oppressive society, but only Lena broke free.

Pandemonium continues Lena’s gripping story. After escaping from Portland, Maine, Lena makes it to the Wilds and becomes part of an Invalid community, where she transforms herself into a warrior for the resistance. A future without Alex is unimaginable, but Lena pushes forward and fights, both for him and for a world in which love is no longer considered a disease. Swept up in a volatile mix of revolutionaries and counterinsurgents, Lena struggles to survive—and wonders if she may be falling in love again.

Full of danger, forbidden romance, and exquisite writing, Lauren Oliver’s sequel to Delirium races forward at a breathtaking pace and is sure to appeal to fans who crave the high-stakes action of The Hunger Games and the bittersweet love story of Romeo & Juliet.

REQUIEM, Book Three
Third book in the DELIRIUM series
Expected publication: March  5th, 2013 by HarperTeen
Now an active member of the resistance, Lena has been transformed. The nascent rebellion that was under way in Pandemonium has ignited into an all-out revolution in Requiem, and Lena is at the center of the fight. After rescuing Julian from a death sentence, Lena and her friends fled to the Wilds. But the Wilds are no longer a safe haven—pockets of rebellion have opened throughout the country, and the government cannot deny the existence of Invalids. Regulators now infiltrate the borderlands to stamp out the rebels, and as Lena navigates the increasingly dangerous terrain, her best friend, Hana, lives a safe, loveless life in Portland as the fiancée of the young mayor. Requiem is told from both Lena’s and Hana’s points of view. The two girls live side by side in a world that divides them until, at last, their stories converge.
