So gooood. So many different mediums for this. Donghua, light novel, drama, etc. Have been reading through the fanfiction of it too. So many really good stories and the fan art is all so pretty. If you like this definitely look up the original authors other stories. MXTX has really good novels. EDIT: I just got the second paperback novel delivered this past Tuesday. I now have two novels of all three published MXTX series! Half way there!

Ah, Mao Mao is very much a cat. I love her character, it is just so different from most heroines. Also the way the information is twined together is great for intrigue. Half the time you don't even know the full mystery until you've read everything. I am also going to buy the novels. You can get them on Amazon Kindle for about $7 (On the Kindle App).
