Addicted to YA discussion

I'm looking for a book to read that's 60-90's YA because that's literally the best genre ever and it's seriously underrated for actually no reason and I've already read almost all of the Judy Blume books

The not so star spangled life of Sunita Seng- Mitali Perkins
Slam book- Ann Martin
Annie on my mind- Nancy Garden

Hope that helps

The Sweet Valley High books by Francine Pascal are 80s YA (High School).

Paul Zindel’s Pigman and The Pigman’s Legacy, Maureen Daly’s Acts of Love. I also like Beverly Cleary’s The Luckiest Girl and Jerry Spinelli’s Stargirl, though not exactly in that period.
