OMG, I was the biggest BSC fan in the entire world. Primary school was just a big BSC experience for me. I have about 70 books, the last being #119. I'm such a tragic - I have the BSC mystery collection, biographies, a couple of the California Diaries and those SUPER SPECIAL books where everyone in the BSC goes on vacation. I still remember that my favourute was the one where they went to Hawaii, and Stacey got into a helicopter crash and couldn't find her insulin.
I'm not ashamed to admit that it was indeed the Babysitters Club that can account for my bookwormish tendencies. Gawd, I even have the movie on tape somewhere.
I remember Abby was a New Yorker who had a twin Anna that had scoliosis and was good at soccer. I didn't even know she disappeared. Or did she? I'm going to have to do some research now, lol.
From Wiki:
Abigail "Abby" Stevenson
Club position: Alternate officer (replacing Dawn)
First appearance: #89, Kristy and the Dirty Diapers (British English title: Kristy and the Nasty Nappies)
Shortly after Dawn moves back to California to live with her father, Abby moves to Stoneybrook from Long Island with her mother and her twin sister, Anna (who turns down the invitation to join the club in the same book); her father died when she was 8 or 9. Abby's love for sports and bold personality often put her at odds with Kristy. She and Shannon Kilbourne are the only other Baby-Sitters Club members who live in Kristy's neighborhood. She has curly black hair and brown eyes, and suffers from asthma and allergies.
