Wow! Throwback memories!!!! I forgot about all those books! I, too, loved Nancy Drew mysteries, the Babysitter's Club (the black girl's name was Jessie, I believe), The Gymnasts series, the Ramona Quimby series, etc.
I was also a fan of any books written by Caroline B. Cooney (The Face on the Milk Carton), Bette Green (Summer of My German Soldier), Judy Blume (especially Just As Long As We're Together), Walter Dean Myers (The Glory Field), Norma Fox Mazer (too many to name!!), and the black lady who wrote books like The Secret of Gumbo Grove and Cousins.
As you can probably tell, I was an avid reader as a kid. In fact, every birthday my parents would give me the choice between getting $100 or having a birthday party. I would always choose the former, and I would spend an entire Saturday afternoon in Waldenbooks buying as many titles as I could by my favorite authors. I miss those days!
btw -- Does anybody remember the Christopher Pike series. Those books were scary for real!
