I'm a librarian who loves anime, manga, and reading a wide variety of genres.
I'm a harsh judge of light novels, and volume 1 was better than I had hoped (although I still prefer the anime). I decided it was time to read volume 2, and our interlibrary loan department delivered it to me today. Yay!
The BookLikes image is the original cover. For some reason, Yen Press decided that their book jacket should have a more realistic representation of Holo (I'd post a picture, but I can't figure out how to do that in the BookLikes "Text" screen). I dislike it, although I suppose it at least serves as a visual cue that this is the novel series and not the manga adaptation.
I must not be the only one who dislikes the more realistic cover, because it's kind of hard to find online. Amazon has the original version, as do Goodreads and Barnes & Noble.
