For me this narrator is better than many others exactly because she sounds as character with emotions and not an audiobook that usually makes me bored. Is she intrusive? - Yes. Does that make me pay more attention to her words? - Also yes.
Plus it seems to me that some of you here are stretching the occasional cases on the whole situation. Don't tell me the narrator sounds seductive when she talks about Timber (the territorial squirrel) for example, that's not true. She sounds clearly seductive when it's about the Absolute, tadpoles, Daisy... so I'm quite sure she represents the unnatural seductive side of the Absolute this way.
