Close to home! This is about a man about my age, living in the same neighborhood as me, also a vegan.
It's been compared to Rosemary's Baby, which I haven't read yet, but my closest point of reference was American Psycho: the inner monologue has the same kind of self-aware neuroticism and the series of events with the glib commentary felt roughly the same.
Overall, the metaphors were too simplistic at some times, too vague at others. Veganism is a storytelling device here, and vegans probably won't be happy with what it says. It felt scattershot topically, rushed.
It's readable and sometimes fun. If you are me, it's relatable on some levels. But it's a novel that's trying to make a statement, and that part didn't work for me.
