Lady of Magick by Sylvia Hunter
In her second year of studies at Merlin College, Sophie Marshall struggles with being the only female undergraduate. While this is helped by her husband, Gray's, invitation to lecture at the University in Din Edin, all is thrown into turmoil when he does not return from a journey to his childhood home in London. Can Sophie, Joanna and their friend Gwendolen Pryce rescue him? Or will Sophie find herself in a far greater crisis than anyone expected that threatens not just Gray, but the entire kingdom?
