I'm making a vampire book, need a name though...?

Ok the book [there is three in my series] is about this powerful vampire, very dark, her name is Snow. She thinks of life as a game, and plays it to peoples dismay, her favorite guest are vampires [no gay-*** animal drinkers, FYI]. This is going to be a gruesome book, lots of tension, blood, dead people, demons, and just plain gore. But instead, it actually has a plot to it. In the first book, two boys are chosen to play, they have to set out and find Snow. They have never heard of her but they can sense that she is strong. All they know is that they can not lose. Second book, two girls are trying to find her for her help. Third one, Vampires get jealous of Snows power. PLEASE HELP ME NAME MY SERIES!!<3
