Order of Delirium Books

American author Lauren Oliver crafts a compelling YA dystopian world in her Delirium series, where romance and fantasy intertwine against a backdrop of oppression. Set in a society ruled by totalitarian forces that have branded love as a dangerous disease, the story follows protagonists Lena and Alex as they struggle against the system to claim their right to freedom.

Oliver launched the Delirium Trilogy in 2011 with the series' inaugural novel. The trilogy reached its conclusion the following year in 2012 with Requiem, though readers were treated to an additional story, Raven, published after the trilogy's completion.
