This was one of my favorite mangas... I think maybe because I read the books first.
And after reading the books, Well, I was still craving more of Alexander & Raven's story.
The manga isn't a continuation (although that would be so cool!), it's a different story adding in more about Alexander's family.
It's great. The art work is fantastic. And I love actually getting to see Raven's amazing outfits!
