Kristy's Great Idea is the first book written and published in the original The Baby-Sitter's Club series. The club is formed by four best friends: Kristy Thomas (club president), Claudia Kishi (club vice president), Mary Anne Spier (club secretary), and Stacey McGill (club treasurer). The book was written by Ann M. Martin and published in August of 1986.
Kristy has a great idea: to form a club that babysits! Kristy and her friends, Claudia and Mary Anne, already baby sit and they consider getting new-girl-in-town-and-school Stacey McGill to join, too. Once everything is decided and the club is formed, Kristy and her friends have wacky baby sitting (like DOG sitting) adventures that they never counted on. Will they give up the club or will they keep trying?
Kristy's divorced mother, Elizabeth Thomas-Brewer, has been dating a new guy, Watson Brewer, and Kristy is feeling cautious about him. He seems like a good guy, but Kristy's real father, Patrick Thomas, walked out on the family, leaving Elizabeth to look after four kids on her own, including a newborn baby (David Michael). Kristy doesn't want to get hurt again and has to decide whether to hate his guts or to open up to him, taking the chance that he'll hurt her, just like her father did to her, emotionally. Kristy must decide whether it's worth the pain to love a new (almost) father again.
Also, Stacey, their new friend, is acting mysterious and Kristy, Mary Anne, and Claudia have to find out what she's up to.
Kristy thinks the Baby-sitters Club is a great idea. She and her friends Claudia, Stacey, and Mary Anne all love taking care of kids. A club will give them the chance to have lots of fun — and make tons of money.
But nobody counted on prank calls, uncontrollable two-year-olds, wild pets, and parents who don't always tell the truth. And then there's Stacey, who's acting more and more mysterious. Having a baby-sitters club isn't easy, but Kristy and her friends aren't giving up until they get it right!
