How to Read the Delirium Books
Read Delirium, Pandemonium, and Requiem in numbered order. Lena's relationships, discoveries, and role in the resistance form one continuous story.
Delirium Stories collects four optional novellas about Hana, Annabel, Raven, and Alex. They add other perspectives but are not a fourth novel; the simplest spoiler-conscious choice is to read the collection after Requiem.

For parents
What Parents Should Know
The society controls relationships through surveillance, raids, imprisonment, propaganda, and a compulsory brain procedure. The trilogy includes executions, torture, fighting, shootings, serious injuries, character and animal deaths, grief, and rebellion against an authoritarian government.
Romance is central, including kissing, jealousy, and a love triangle, but the larger questions concern consent, freedom, and whether safety is worth enforced emotional control. The danger becomes more sustained after the first book.
