The Angel of Potters Row (Of Love and Arrangement #4)
Alice Lockley

Yet she is famous, a champion of the poor, she is a thrilling tale to read of, and on the lips of all good society.
Grace Newbury, maligned, unwanted, and unhappy, was rapidly approaching spinsterhood. But Grace had a secret, a dangerous one, one that a husband definitely wouldn't approve of, and one that would cause yet more trouble, more than that, ruination, not only to her, but her whole family.
When Grace meets Sir Percival, in the midst of her worst humiliation at the hands of her four sisters, her life shifts, and things begin to change. In truth, she knew that her double life, the lies, and the lengths she went to in order to keeps secrets were wearing her down.
Being The Angel of Potters Row had once been a thrilling and noble calling, but infamy and her family's continual contempt for her were warring within.
Something had to give, and it was set into motion by a tall dark gentleman, causing Grace's world to come crashing down.
Of Love and Arrangement are an interlocking series of stand alone historical novels, following the paths of men and women in the nineteenth century, and though not necessary, they are best read in order.
