I don't usually read graphic novels, they just aren't my thing. I also don't really watch cartoons (anime). Anya's Ghost is a manga, and it was actually pretty good. I didn't go in expecting much, but I think there is a lesson to be learned.
Anya is the daughter of a Russian immigrant who struggles at a private school. She wants to fit in, but because of her background it makes it difficult. She doesn't use her real name outside of her home because it embarrasses her; it's Annushka Borzakovskaya. She doesn't like going to church because of how "Russian" it is. She has one close-ish friend, Siobhan, who teases her a lot and encourages her to smoke and skip class. Generally, she hates her life... until she falls down a well; that's when she meets Emily.
I feel like there is a moral to this story; love yourself, be true to yourself, and respect your heritage. Also, don't fall down wells and bring crazy ghost girls home.
