Mental illness is a major part of the story and it explores it from the viewpoint of Charmaine as well as from the viewpoint of those who believe mental illness is a symptom of the lack of God in life, rather than a genuine illness.
Songbird is Christian fiction. It explores Charmaine's experience of God through the love of her foster mother, the love of her husband, as well as through the pain of her depression and the losses in her life. I wouldn't call it preachy and it certainly isn't one of those books that implies that if you have enough faith, then everything will be alright. I definitely recommend it.
