Pandemonium is the second novel in the Delirium Trilogy.


After falling in love, Lena Haloway and Alex Sheathes 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. Although she is bereft of the boy she loves, her struggles seem to be leading her toward a new love.


The novel is split into two narratives; "Then" which describes Lena's struggle for survival in the Wilds and "Now" which describes her work for the resistance in New York .


Day by day she gets better and begins to learn the ways of the Wilds. She learns that life here is harsh because the people have so little and have to struggle to survive. But she also makes friends amongst the people, especially with Hunter and Sarah.

As winter draws in, the whole camp must move down south in order to survive. Several of them go ahead to plant food for the camp, including Hunter and Raven's lover, Tack.

All seems well until Lena, as one of her jobs, checks the bird nests for communications from sympathizers in the verified communities. She finds the bird feathers slick with red, meaning danger, and she runs to warn the others as bombs fall from the sky. They only learn later that these bombings occurred as a retaliation for the Incidents; a series of lethal bombings by the resistance in verified communities.

Their homestead is destroyed along with several of their people missing, and presumably dead, as they have to begin their journey earlier than planned with less supplies than they planned. As a result, Raven's adoptive daughter, Blue, becomes ill and though they try everything to save her, she dies. Raven becomes grief-stricken.

Their journey grows worse as they realize their last supply of food has not been planted by Tack and Hunter meaning that both are probably they dead. However, when they are attacked by scavengers and are almost annihilated, Tack and Hunter show up to save them and the entire camp manages to get to safety.

Now: Several months have passed and Lena Haloway has joined the resistance along with Tack and Raven, are working in New York, observing the Deliria-Free America (DFA)--an anti-deliria organization gaining much attention--as well as the leader's son of the movement, Julian Fineman.

On the day of a big rally and just before the time when Julian is supposed to be cured, a group of scavengers break in and cause chaos while also taking Julian and Lena as hostages. Julian and Lena are at first hostile to each other in their cell, especially since Lena sees him as the part of the people who killed Alex. However, the two begin to warm up to each other and reveal things about their pasts. This is once more broken though when Lena reveals that she is in fact an Invalid and Julian is disgusted.

Lena manages to knock out one of their captors and with Julian's help, they are both able to escape into the tunnels (in reality the old subway system of New York). Julian eventually reveals to her the full extent of his father's anger and hatred and how Julian himself thought that staying on the proper path would save him. Lena tries to encourage him that there is a better way but remains to have conflicting thoughts about Julian as she grows to love him but doesn't want to betray Alex's memory.

With the help of a community of Invalids living in the tunnels, they manage to get to a homestead called Salvage where Julian and Lena finally allow themselves to fall in love and the two share their first kiss. The next morning, regulators come in to arrest them though the regulator with Lena turns out to be a member of the resistance, one who won't allow Lena to see her face.

Lena returns to the Wilds where Raven and Tack reveal that the entire event was a test to learn her true loyalty to the resistance and to convert Julian to their side by having him fall in love with Lena. Julian has not been saved by the resistance and will instead by executed in New York for refusing the cure while showing signs of the deliria. Disgusted, Lena leaves the resistance and Raven and goes back into New York to save Julian. While there, she finds information that reveals her mother was the regulator who saved her life but refused to show her face.

Lena makes it into the room which Julian is about to executed in but realizes it's too late for her to do anything. Just as Julian is about to be killed, Raven comes in and her and Lena manage to free Julian while also killing his father in the process.

They all make it back to the Wilds where Julian and Lena kiss once more and Lena promises to stay with him forever. A voice behind them says, "Don't believe her," and Lena turns around to see Alex behind her, alive and well once more.


  • Lena Haloway (sometimes using the alias Lena Morgan Jones) - The protagonist. Now eighteen and having rejected mainstream society and its cure, Lena joins the Invalids and the resistance, in the process leaving the old Lena behind and reinventing herself into someone harsher.
  • Julian Fineman - The only living son of the DFA's leader, he is expected to receive the cure even though it might very well kill him after all the surgeries he's had in the past from cancer.

His character is added to Delirium (TV Series) despite his story not starting until the second novel. He is played by Gregg Sulkin.

  • Thomas Fineman - Julian's father. As the founder of the DFA, he believes in order and purity without deliria and is bent on doing anything to make it so, including violence. Despite first appearing in the second book, he appears in Delirium (TV Series) played by Billy Campbell.
