I'm relishing the way the narrator does things her own way, with a sort of gleeful defiance of literary conventions.

For example, instead of being reserved about characters' functions in the story, and letting the reader work them out, she casually tells us outright in volume 1 that there's a hero, and who he is: ..., my heroine was most unnaturally able to fulfil her engagement, though it was made with the hero himself. (ch14)
