Can you help me remember the Title of this book? (description inside)

Hi. I am hoping to find out the title of a book I read awhile ago. I’m not sure if it is possible as the details I remember are foggy and scattered. But I want to try. When I read it there was a girl’s name in there. I remember thinking ‘this is what I’m going to name my first girl’. And I did. I would love to buy the book for her as a keepsake.

Details I remember: (or kinda remember anyway…)
A couple moves to a new town. I think they had a miscarriage or loss of some sort but for a lot of the book they only elude to it before it finally comes out. I am remembering they are people-of-color for some reason and am not sure if that is important in the book or something I am imagining. One of their town friends ends us getting very ill. Her best friend is cold and mean (Piper). But turns out to be really great. She helps the husband of the sick woman. Then after the sick woman passes away the best friend ends up getting with the husband. The main character and the best friend are at odds for a bit of the book but at the end become friends. (that’s it, i know, i know not much but i thought i’d give it a try anyhow). Thanx!
