"Dawn can't wait for her trip to California. Aside from all the sun and fun, it's her first visit since her brother, Jeff, moved back to live with their dad. California is better than Dawn ever remembered it. The beaches are beautiful, the local theme park is a blast, and Dawn is enjoying all her favorite foods. Plus, Dawn's best friend, Sunny, has even started her own baby-sitting club! Things are going so well that Dawn begins to wonder if she might want to stay in California with her dad and Jeff. Dawn is a California girl at heart, but could she really leave Stoneybrook -- and her mom and The Baby-sitters Club -- for good?"--Publisher.
