Hello, I am trying to figure out what book this is that I remember. It's a historical romance- maybe by Cassie Edwards? And there are spoilers for the story in my description, just a warning.

The main plot centers around a Native American (chief, I believe), his two wives, and a white woman that he wishes to make his third wife. In regards to his two wives, both are Native American and one of them is pregnant and -spoiler alert- it is revealed after she is murdered that the baby was not her husband's but actually a child conceived with a close friend of his. The man she had the affair with lets it slip while holding her dead body and babbling about it right in front of her husband. The other wife was vicious to the pregnant wife, getting banished after she cut off the pregnant wife's braids, and I believe that she wound up prisoner to some evil white guy that wanted the white woman. As for the white woman, she was not happy about the Native American already having two wives and wanting to make her the third, though the Native American conceded to her wishes enough to start work on a separate home for her so she wouldn't have to share with his other wives. She did try being nice to the pregnant wife, though the pregnant wife pouted and sulked about her husband's plan to marry the white woman. At the end of the book, the white woman is the only wife and the Native American man agreed not to marry anyone else.

If anyone knows what book this is, please let me know ; ; I have been trying to find it for months with little success.
