I read the Delirium Stories because I didn't want to leave the world of Delirium so soon. This collection of stories is a great source of closure.We get to know more and be in the lives of three characters who, in my opinion, didn't shine so much in Requiem. These characters are Hana, Annabel and Raven.Hana's story really opens your eyes to Portland. Annabel's story reveals more of the past that wasn't told. And Raven's story shows her past in being in the Wilds and her hopes for the future.Really, these stories aren't necessarily needed for the main story, but it definitely gives you a bigger sense on what's going on with these characters. And like I said, it's a nice closure too.But I really love Oliver's style of writing and some parts of the stories did pull on my heart strings a bit so I still enjoyed reading Delirium Stories. Even, if it may not be needed entirely.
