Suggest me a fiction book that centers around grief…

I read a lot of immigrant stories and have been trying to have a new gateway to cultures. I've read a lot books from different cultures like the works of Elif Shafak, Susan Abulhawa, Rohinton Mistry, Khaled Hosseini, Yaa Gyasi, Zoulfa Katouh, etc.

I am at a difficult phase in my life and relatability might be welcome.

I prefer fiction but nonfiction book written like stories are welcome too.
