About This Book
The sharp clatter of footsteps echoes through the narrow London streets, mixing with the faint smell of old books and rain-soaked pavement. Joe’s heart pounds as he uncovers secrets about his grandmother—secrets darker than her scowl and colder than the winter air. What if the person you trust most is hiding a dangerous secret?
Quick Assessment
Set in London, this middle-grade adventure follows twelve-year-old Joe as he navigates a surprising and sinister secret about his grandmother. While the story includes elements of mild peril and suspense, it is appropriate for readers aged 9-12 and explores themes of trust and family dynamics. Parents should note some scenes involve tension and mystery but no graphic content.
