Regan is Ron and Deborah’s daughter and Carson’s brother. Regan inherits her mother’s faith and practicality, spurning the nice clothes that she is offered by her parents in favor of secondhand clothes from Salvation Army. Although she tries her hand in her father’s world of art dealing, Regan finds it dreadful and decides to commit her life to faith and ministry, ultimately working as a cook at a Christian camp in Colorado. Regan is a young adult during the ten years in which most of the narrative takes places, and so plays a comparatively small role in the story, though it is confirmed that she comes to see Denver as much a part of the family as Ron does.
