What was the point of The Half Moon by Mary Beth Keane?

I read this book because I remember liking Ask Again, Yes! by the same author. It's not that I didn't enjoy The Half Moon and I did find good things about it, but I keep mulling over the questions, What was I supposed to get out of it or What message did the author intend to convey or Is there a moral to this story? The question for you all is, Did you think there was a point to this novel or was it simply a slice of life? I'm okay with the latter because I appreciate reading for entertainment and realize I could be overthinking it.
