Callie's Castle introduces Callie Cameron, who is unhappy with her friend Frances, her family and, well ... life. With her brothers and sister running riot through her bedroom, reading her diary and ruining her treasures, she's desperate for a space to call her own. Even the promised new house is proving to be a letdown, until her beloved grandfather helps her find a solution. In Callie's Family, we return to the Cameron household, with new dilemmas arising as the kids grow up. Callie hates the thought of having to give up her 'castle' to her brother Dan, now she's getting older. And there's an adventure in store - a trip to Denmark to meet their cousin Marius - but only one ticket. So which of them will go: Callie or Dan?
