Highland Rising (The House of Pendray #4)
Anna Markland

Faith Cameron is the daughter of a man executed for treason and a mad mother who took her own life. Fostered into the Pendray family, she has longed for Gray's return, though she realizes she isn't a suitable match for the son of a noble family.
Gray is immediately drawn to Faith whom he discovers has grown into a beautiful and courageous young woman—but he has made commitments to the daughter of his mentor in Edinburgh. Can love find a way to overcome the divide between them and triumph over the dangers and betrayals of a rebellion?
