The Ravening3 books in series
The world didn't end with a bang, it didn't go out in a ball of fire and fury, nor did it end in ice. But in some strange way, ice was the end - or maybe it was the beginning of something more.
When Bethany finds herself suddenly alone in a world that was alive only moments before, she flees into the streets of her town in search of her family. Panicked by the immobile people surrounding her, she is almost captured by the monsters hunting her until Cade steps in.
Dark and distant, most people at Bethany's school are wary of Cade yet oddly fascinated by him. Bethany and he had been close as children, but it has been years since she's had any real contact with him. As their situation becomes even more perilous, Bethany struggles to come to terms with her past, her terrifying new reality, and her growing love for a boy that is powerful, mysterious, and perhaps even more frightening than the aliens hunting them - aliens that want more than their lives: they want their blood.
