Throne of Grace by Cecily K. Wolfe

Can a newly Christian young man convince his mother's maid that his love for her is worth more than his inherited life of luxury? Josie is content as a maid in a rich cottager's mansion along the Cliff Walk of beautiful Newport, Rhode Island, but the arrival of her employer's handsome, pensive son tempts her into a relationship that while chaste, is forbidden between their social classes in the Gilded Age of 1893. After travels abroad have led Arthur in search of a deeper connection with his Lord, he returns home to find love with his mother's maid, a Christian girl with a heart full of love and charity. Can they overcome their families' refusal to accept their attachment, or is their relationship doomed from their very first meeting on the romantic Cliff Walk?
