Abby's Twin - Martin, Ann M

Even though they look alike, Abby and Anna act so different! Outgoing Abby walks all over her quiet twin. Still they're twins, and twins ALWAYS stick together, right? Wrong, Anna has a serious problem - and she doesn't want any help from Abby. In fact, Anna's just shutting her sister out.
