The follow-up to "Delirium." After falling in love, Lena and Alex flee their oppressive society where love is outlawed and everyone must receive "the cure"--an operation that makes them immune to the delirium of love--but Lena alone manages to find her way to a community of resistance fighters.

The second book in Lauren Oliver's remarkable New York Times bestselling trilogy about forbidden love, revolution, and the power to choose.

In this electrifying follow-up to Delirium, Lena is on a dangerous course that takes her through the unregulated Wilds and into the heart of a growing resistance movement. This riveting, brilliant novel crackles with the fire of fierce defiance, romance, and the sparks of a revolution about to ignite.
