I loved 95% of this book, and will be coming back to it in the future.

One of the things I especially liked was that the lesbian relationship was incredibly obvious, but none of the characters seemed to have much a problem with it, despite the cultural attitudes of the time this book was published.

I only wish it were longer and gave more detail on the time they spent together, though I do understand this is intended to be read as a letter to the reader.

The only bit I don't like is the implications around the "vision" that starts the book.

Laura, the narrator, is 6 at the time this vision happens, which involves the (by that point) 150+ year old Carmilla being very intimate with her. Carmilla does later say that for her side of the vision, she saw Laura as an 18 year old not a 6 year old, but it still weirded me out to think about it.
