No Place of Angels by Meg Hutchinson
Carys Beddows has never understood why her mother hates her so much. Certainly jealousy plays a part: Maria believes that young Ryder Tempal would be hers with her pretty daughter out of the way, and throws Carys out of the house to fend for herself. Befriended by Alice, a young woman in domestic service, Carys herself takes a job as a housemaid and is lucky enough to find in the mistress of the house a friend and patron. Maria continues with her vicious schemes until fate intervenes to punish her wicked ways; but for Carys, the reward of virtue is lasting love.
