Then there's 'An Echo in the Darkness' which is the sequel to 'A Voice in the Wind'. It continues the story of the characters from the first book, further exploring the themes of love, faith, and survival in the ancient Roman world. The relationships between the characters, both romantic and platonic, are really well - developed.
I also like 'The Preacher's Bride' by Jody Hedlund. It's set in 17th - century England. The story is about a young woman who marries a preacher. It shows their journey together, with all the difficulties they face in a Puritan society, and their growing love for each other. There are also spiritual elements that add depth to the story.
Sure. 'A Voice in the Wind' by Francine Rivers is excellent. It's set in Rome during the first century. The main character, Hadassah, is a slave. Her unwavering faith and her relationships, including some with romantic undertones, make for a captivating story. It gives a great view of early Christian life in a non - Christian world.
