Archie is used to being top of his class, with his quiet genius and superhuman focus, but when a top-secret opportunity comes his way, he is tested to his limits. Is the 13-year-old up to the challenge? Live the story with Archie every step of the way, through adventure, challenges and mystery, and even have a go at solving some puzzles included in the book. A portion of the proceeds from this book will go to the Honeypot Children's Charity which supports amazing young carers in the UK aged 5-12 in their work caring for ill family members.
