The Secret of the Underground Room (2011) Parents Guide: Is the book OK for kids?

There is no sexual content in this book. Relationships are strictly platonic friendships or mentorships, maintaining a focus on the mystery and the historical setting of the early 1950s. The bond between Johnny Dixon and Professor Childermass is centered on academic curiosity and mutual protection.
