This is one of those books that genuinely earned its bestseller status—the concept is original, the photographs are haunting, and the mystery keeps you turning pages. Riggs created something distinctive in a crowded YA market.
That said, parents need to know this skews darker and more explicit than the 'Peculiar Children' branding might suggest. The profanity is pervasive (multiple reviews call it out specifically), and the violence and death scenes are graphic enough that several parents recommend 15+ rather than the 12+ that kid reviewers suggest.
If your teen loves dark fantasy, atmospheric horror, and can handle mature content, this delivers. It's got real themes about trauma, identity, and belonging wrapped in a propulsive thriller. Just don't hand it to a sensitive 11-year-old expecting whimsical Tim Burton vibes—this is legitimately creepy and intense.
