After the dawn ritual on her eighteenth birthday, Cassie is welcomed by those of Abraham's pantheon. While she knows she isn't a Walker no one is quite willing to tell her exactly what she is other than 'family'. They are excited about the skills she might develop as her training begins and she realizes that she is the latest entertainment to break up the long monotony of their eternity. As she struggles to maintain her place in the regular world and complete her midterms, the mystical world and her newly developing abilities threaten to intrude. The line between her separate worlds is thin and beginning to blur. How long can Cassie remain a part of both?
