The most notable structure used in Marie Lu’s writing is her use of dual or multiple perspectives. By telling a story with 2 or more perspectives it allows the readers to see what happened and take in a broader understanding. 

Examples of this structure can be seen in Marie Lu’s “Warcross” Novel where we see the perspectives of Emika and Hideo. In Emiko's perspective readers are taking in the adrenaline and challenges of participating in warcross while in Hideo’s perspective we get to see into the mind of the creator of Warcross. Together they bring Warcross into full perspective while also offering the readers the personal insight of both Emika and Hideo. With Emiko saying stuff like,"Participating in Warcross is like diving into a virtual reality world where anything is possible and the stakes are higher than ever before. It's exhilarating, terrifying, and utterly consuming." While Hideo is saying, "To make Warcross was to create a world. To play Warcross was to live in it."

Another example of this structure can be found in "The Young Elites'' series in which Lu uses multiple perspectives to explore the relationship between a group of supernatural individuals. Using alternating perspectives between different characters such as Adelina, Enzo, and Raffaele, Lu creates a varying narrative. 

Overall, the use of dual or multiple perspectives for Lu’s writing structure gives the readers the ability to take in multifaceted perspectives on the characters.
