Goodreads has a synopsis and a cover for Pandemonium, the follow-up to Lauren Oliver's Delirium (you can read my review of Delirium HERE).
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.
