Whilst it's quite unique to write a book from the point of view of a senile lady with severe memory loss problems (Alzheimers, not specified, though) it is utterly imperative to write it in a way that isn't utterly boring, slow and, well, like the narrator has Alzheimers. It is obviously repetitive and full of inner monologue so droll I went and looked up spoilers because I couldn't bring myself to read the rest of it. 
 I appreciate what the author tried to do, but she failed miserably. In my humble opinion, of course. Obligatory apology for having an opinion, of course.
