At sixteen, Lady Victoria Mansfield, youngest daughter of the earl and countess of Fairmount, is destined for a charmed life and her choice of mates worthy of her status. Then she makes a terrifying discovery that will ruin her life and disgrace her family forever. Tory's blood is tainted... by magic.

When a shocking accident forces Tory to reveal her despised skill, she is immediately exiled to Lackland Abbey, a reform school for young men and women in her position. Tory's greatest wish is to be cured so she can return home and perhaps recover some of her shattered life.

Instead, curiosity and the lure of magic lead Tory to rebel students who have pledged their talents to protect England. As she joins them in their secret studies, she discovers her full powers - and is drawn to the handsome, enigmatic young Marquis of Allarde. But Allarde'a reserve and haunting secret keep him away, though she can see equal longing in his eyes.

Then Tory's pledge sweeps her and her friends into a perilous world of danger, challenge, and a triumph that saves Britain from conquest. Can danger also bring Tory and Allarde together, despite all that stands between them?
