Something for my 29th birthday

I feel like this is a vague request but I'm not exactly sure how else to put it: I turn 29 in a few days and am looking for something to read while I spend the day in a hot spring on my birthday and then at a nice restaurant by myself (intentionally.)

Over the last year, I went through an awful breakup, changed careers, got a dog, and had some other massive life changes. I'm looking for something in one of two categories: comforting and reflective, maybe? Or just a nice vacation read. I feel like that's pretty vague, but I'm hoping someone can relate to these life circumstances and recommend something!
