Subversive: Book One in the Clandestine Magic trilogy
In an America controlled by wizards, Beatrix Harper counts herself among the resistance—the Women’s League for the Prohibition of Magic. Then Peter Blackwell, the only wizard her town has ever produced, unexpectedly returns home and presses her into service as his assistant.
Beatrix fears he wants to undermine the League. His real purpose is far more dangerous for them both.
