Suggest me fiction books for women in their 30s

I'm not looking for:
Romance (if you really like a romance & it doesn't have smut in them, then it's fine)
Fantasy

but i want realistic fictions:
feel-good
Adventure
Life-lesson books.
Maybe about friendship
Moving on after a breakup

Also, a shorter book, less than 300 pages.
And could you add a short description?
