When James Walker arrives at Tudor College, Cambridge, he tries to create a vague air of mystery about himself in the hope of making the right kind of friends. By accident or fate he encounters a member of the Night Climbers, a wealthy, secretive, and tantalizingly eccentric circle of undergraduates who scale the college towers and gargoyles at night in pursuit of the kind of thrill-seeking danger that makes them feel truly alive.
Seduced by their reckless charisma and talent for decadence, James falls for both Francis, the group’s ringleader, and Jessica, his beautiful best friend. Their extravagant living is financed, unwittingly, by Francis’s father, but when he suddenly cuts his son off, the friends are left floundering as they try to maintain a lifestyle they can’t afford. That is, until Francis embroils them in a plan that will test the limits of their friendship and link them to one another forever.
