Read this book awhile back and I want to read it again but i can't remember the name >< Well here's the description.

The main character is of mixed heritage Japanese and something else(she mentions this so hey sorry if i offend someone)She is the only remaining member of her family after the apocalypse which was simply a gray toxic cloud from space that destroyed everything more or less and wiped out enough humans for the vampire to take over. The story starts with her hiding in an old bomb shelter bunker in New York i think (her family had been there for an art expo) and she goes for supplies almost gets caught by a vamp(most of which look inhuman and have one main claw i think its either the index or middle finger) she almost saves herself but fails kinda and gets saved by an African American man who's name i can't remember. He teaches her the ropes finds out shes a dead aim and ambidextrous oh later she also proves she is partially insane but that makes sense all things considered. She also meets a vampire fighting nun(she might of been saved by the nun its been awhile since i've read the book) I can't remember ANYTHING else but the story line (i really wish i could remember character names i could find it then lolz) well hopefully you guys(and gals) can help :D thanks and cya laterz
