A chance meeting and a secret message drags Libby into a thrilling mystery, but no one believes she can spot the clues. Can she make them realise what she is really capable of, before it's too late?
Libby is visually impaired but that doesn't stop her being a keen photographer. She loves going out walking with her guide dog, Samson, and taking photos, but her family worry about her - and Libby wishes she could be more independent.
The day that the boy gives her a secret note to deliver changes everything. Because soon after, the boy goes missing, and no one - except Libby and her new friend Kyle - thinks there is anything to worry about.
Libby knows there's no way her parents would let her get involved. But what if she's the only person who can solve the mystery...?
