April Dunne is having a rough time.

There are vampires in her school. Not Goths, or Emos in fancy dress. Dangerous, blood-sucking semi-immortals. They run the school. They pretend to be students at it. And they're using their influence to recruit smart, rich students - aka 'bleeders' - to their own cause.

What is that cause? April isn't sure. But she knows they killed a rock star for it, and innocents who got too close to the truth. One of them almost killed her.

But that's nothing to what's coming next. Gabriel, her kinda-boyfriend, is dying and unless April can find a cure then not only is she going to be boyfriendless, she's also going to lose one of her major allies in the school. And she really needs allies. Because it turns out April has an ability of her own, one that could prove lethal to the 'Suckers' who've taken over the school. If any of them figure out what she is, then losing her boyfriend will be the least of her problems ...
