About This Book
Reach for this book when your child is craving a sense of real-world competence or struggling with the friction between rigid adult expectations and their own growing need for autonomy. This classic adventure follows the Blackett sisters and the Callums as they navigate a high-stakes summer of 'living double lives' to avoid the disapproval of a strict Great Aunt. It is a masterful exploration of resourcefulness, secret-keeping for the sake of friendship, and the quiet dignity of mastering practical skills like sailing and survival. While the setting is historical, the emotional core addresses a timeless developmental milestone: the transition from being cared for to being capable. It is perfectly suited for independent readers aged 8 to 13 who appreciate slow-burn realism and stories where children, not adults, solve the problems. Parents will value how it models accountability and the rewards of hard work without being didactic.
