Dark Mirror: The Lackland Abbey Chronicles: First Adventure

Sixteen year old Lady Victoria Mansfield is the cherished youngest child of a lord, and she is destined for a life of wealth and privilege. But Tory has a shameful secret—a secret so powerful that, if exposed, it could strip her of her position and disgrace her family forever. Tory's blood is tainted...by magic. When a shocking accident forces Tory to demonstrate her despised power for all to see, she's immediately exiled to Lackland Abbey, a reform school for aristocratic young men and women who are cursed with magical power. There she can be cured of her deplorable talents and maybe, if she's lucky, be able to return to society. But all Tory has known and believed will be challenged at Lackland as she discovers friendship and love with fellow students who call themselves Merlin's Irregulars, and are pledged to defend Britain whatever the cost. Even if that means traveling through time to face the guns of Dunkirk.
