2025 Reading Challenge discussion

I really thought this book was well written, and I enjoyed reading it. It did however have more sex than I was comfortable with,(view spoiler)[ especially the affair the aged character had with a fourteen year old (view spoiler)[.I nearly recommended it to several people, and I'm glad I waited until I had read more. I thought the author described young love, marriage over many years, and aging accurately. The description of Columbia during the late 19th century and early 20th century was good too. (hide spoiler)] (hide spoiler)]

what book??
