What are some good fictional books about dissociative identity disorder?

I, being someone who has BP1, enjoy reading books about mental disorders or whatever title you would like to call it. Books like She’s Come Undone by Wally lamb comes to mind. Fantastic book. I would love some suggestions. I’d prefer fiction. I’ve read a lot of biographies and non fictional tellings. But I enjoy watching an author create a fantasy character and world. Thanks
