The Rose Society is a fantasy novel by American author Marie Lu released on October 13, 2015.

The story follows Adelina Amouteru as she embraces her notorious newfound identity as the "White Wolf" and undertakes to form a new 'society' to rival the Dagger Society, whose remaining members expelled her, and the anti-malfetto government.

Lu revealed in various interviews that she felt uncomfortable writing The Rose Society as it explored Adelina's more psychotic side, stating that she was scared that nobody would want to read a story with a character as "unlikeable" as Adelina, and she struggled to make it look reasonable and not just a symptom of pure insanity.

She compared Adelina to Darth Vader stating that she initially thought it would be "fun to write from Darth Vader’s point-of-view", but eventually realized that she was instead exploring the darker, more complex sides of psychologically unstable villains.

Amouteru strives to form a new 'society' composing of only the strongest malfettos, which includes Magiano and a discarded Dagger.
