Suggest me a book that will make me feel good

Hi! My boyfriend is going away on a trip this week and unfortunately i'm a super anxious person and I worry a lot about something happening to him while he's away (I am actively in therapy working on the issue though!). Normally, I love to read thrillers, but I feel like that would just enhance my anxiety. So I'm looking for a book to make me feel good – think easy beach read, maybe a little funny, a cute romantic story or something like that. Entertaining, light and not too emotional. Do you guys have any suggestions? 🙂
