- there are no official or explicit themes of either mental illness or psychosis in the book, however much of the novel is the narrator processing and reflecting on their deep grief, and for a large (very metaphorical) chunk of the book they are very detached from reality in a dissociative way that some do after experiencing trauma — I wanted to give a paranoia/delusions content warning for that portion of the book that it dips in and out of reality and can be quite disorientating. - other than that, the way the author deals with things that may qualify for one psychiatric diagnosis or another, is very holistic and de-pathologising/de-stigmatising as it is framed as part of the human experience for many people. No ableism or stigma applied by author.
