The New York Public Library. A silent sanctuary of knowledge; a 100-year-old labyrinth of towering bookcases, narrow aisles and long marble hallways. For Doctor Stephen Swain and his daughter, Holly, it is the site of a nightmare. Because for one night this historic building is to be the venue for a contest. A contest in which Swain is to compete - whether he likes it or not. The rules are simple: Seven contestants will enter, only one will leave. With his daughter in his arms, Stephen Swain is plunged into a terrifying fight for survival. The stakes are high, the odds brutal. He can choose to run, to hide or to fight - but if he wants to live, he has to win. For in this contest, unless you leave as the victor, you do not leave at all.
