It's fun to be a Baby-sitters' Little Sister! Karen loves to spell words. She is very good at it, too. First she wins the spelling bee in her class. Then Karen wins another spelling contest. And another . . . and another! Soon Karen might be the best junior speller in the state of Connecticut. She's even going to be on TV! Karen thinks that is so great. But her friends don't. They think Karen is a show-off!
