Mark Vogel is like the older brother Stefan Riley never had, until one day he disappears, and Stefan has to adapt to life without him. But, one year later, when he runs into a girl who looks near-identical to Mark, Stefan becomes obsessed. He discovers that other boys have disappeared, too, dozens over the years, most of them students of the Royal College of Saint Almsworth, many of them troubled or unruly before their disappearance.

What is happening to these boys? Who are the handful of women on campus who bear a striking resemblance to some of those who went missing? And what is the connection to the mysterious Dorley Hall?

Stefan works hard to get into the Royal College for one reason and one reason only: to find out exactly what happened to the women who live at Dorley Hall, and to get it to happen to him, too.
