Spoiler for Future speculation judging from opening theme vs novel.:

I think the next story arc will probably be book 5. There's a dancing scene in the novel (book 5), which the opening scene has horo dancing as well. The dancing scenes in the anime where Horo and Lawrence took part in the festival (book 3 comparison) are probably left out when compared to the novel, and probably placed in the flashback.
