This is an OK Western romance novella, but I had a difficult time believing Estelle could ever pass as white. Extreme racism was still very common in that time period, and very few people would have accepted that Estelle could marry a white man or adopt a white child. Estelle, Graham, and Tim would probably have been ostracized and perhaps even suffered violent abuse by racist groups. (Sad to say, racism is still a big problem today ...).
I liked both Estelle and Graham, and thought they were good together -- but I just didn't buy that they would have been free to marry and adopt Tim. They would have continued to suffer all kinds of abuse (and possibly violence), as long as they stayed together. It is unlikely that Graham would have ever been able to start a successful business, or that Estelle would have been accepted by his family and friends.
I liked little Tim a lot, and enjoyed that Estelle and Graham both loved him almost immediately.
If you can get past the fact that their romance just wasn't very believable for that time period, you might enjoy this story. It gets 3 stars from me.
My rating system is below.
1 star -- Hated it, or did not finish. I usually only give this rating if some of the content is truly objectionable to me, like if one of the main characters does something really awful, and gets away with it.
2 stars -- Didn't like it. This rating usually means that I thought the writing wasn't very good, the editing was terrible, I didn't like the characters, or it had other major flaws.
3 stars -- I liked it, but had some minor issues with it. This rating means that there were minor editing issues, the story needed more character development, it was just too unrealistic, or had some other fairly minor issue. The majority of books I read get this rating – I do not consider it a bad rating.
4 stars -- I liked it a lot. This is a high rating for me, and I rarely give a higher one.
5 stars -- I loved it, and will probably read it again. Very few books are good enough to get this rating from me. The ones that do are usually classics.
