In the latest novel from the author of Lady of Magick, Sophie and Gray Marshall must save the Kingdom of Britain from a tide of dark magic....

Three years after taking up residence at the University of Din Edin, Sophie and Gray return to London, escorting the heiress of Alba to meet the British prince to whom she is betrothed. Sparks fail to fly between the pragmatic Lucia of Alba and the romantic Prince Roland, and the marriage alliance is cast into further doubt when the men who tried to poison King Henry are discovered to have escaped from prison.

Gray sets off to track the fugitives abroad, while Sophie tries to spark a connection between the bride and groom by enlisting them in her scheme to reopen a long-shuttered women's college at Oxford. Though a vocal contingent believes that educating women spells ruin, what Sophie and her friends discover in the decaying college library may hold the key to protecting everything they hold dear--as well as a dark secret that could destroy it all.
