There’s trouble brewing when Karen organises her first sleepover … Karen isn’t sure what activities to do when she holds her first sleepover, so she asks her big sister, Kristy, who comes up with some great ideas. So it’s settled: Karen and her friends are going to tell spooky stories, bake cookies, and raid the refrigerator. But then Karen and her best friend Nancy get into a big fight, and Karen doesn’t want Nancy to come to her party anymore. A new girl, Pamela, comes instead but she isn’t any fun. What is Karen going to do?
