La città segreta (2008) Parents Guide: Is the book OK for kids?

This category is entirely absent. The Thea Sisters—Nicky, Colette, Pamela, Paulina, and Violet—share a bond rooted in platonic friendship, sisterhood, and academic collaboration. There are no romantic subplots, flirtations, or suggestive comments throughout their journey to Peru. The narrative focus remains strictly on the archaeological mystery and the team's ability to solve problems together.
