Catherine House is an American college with a difference. Only the most brilliant minds enter, and its graduates earn prestige, wealth, and honour. But over the three years they attend the school, they remain within its black gates; they have no contact with their loved ones; no association with the outside world. Those who break these rules will find themselves facing time in the school's infamous tower. Ines enters Catherine House on the run from an incredibly dark secret, and welcomes the school's isolation. Sharing a room with the sweet, damaged Baby, she slowly begins to build the group of friends she never had outside its walls. One day, however, Baby is summoned to the tower - and never returns. Ines is heartbroken, left to uncover the secrets that Catherine House conceals while slowly becoming more and more seduced herself by its dark, magnetic power.
