Summer Beach Reading Books!

I'm headed to the beach next month and need some new reading material!

I'm looking for older, 80s/90s books about vacation or summer or coming of age stories. Stuff along the lines of Summer Sisters by Judy Blume.

Nothing against newer titles, but I just can't get into the books from authors like Colleen Hoover or Taylor Jenkins Reid… If there's anything NEW that's got substance, please recommend 🙂
