Where can I buy Kaori Yuki books/mangas? And is she the author of the following

[Elizabeth]

titles...? I know I can buy them on Amazon, Barnes and Noble, Borders, Ebay... but where else can I purchase them? I want to buy entire collections at a time (I.E. I want to buy Angel Sanctuary all at once, and then Godchild or The Cain Saga all at once, for example) And those places don't carry all of the collections.

Also in addition, can somebody tell me all the books/mangas that Kaori Yuki has produced?

So far on my list I have...
Angel Sanctuary, Godchild, The Cain Saga, Fairy Cube, Perfume Master...

and did Kaori Yuki produce these?
Kurohime, Cruel Fairytales, a Coeur ouvert, Du bo jue Baiyin, Xiaio Nian Can Xiang, Sha li wang guo, Jie Yin, Sareiki Okoku, Tenshi Kinyo-ku(or Kinyo-hu), Can Ku Detong Hua, Gravel Kingdom.

Any help is appreciated, so even if you can only answer part of the question I'd really appreciate it! Thank you!
