Young readers in Southwark, London UK joined MG Harris in celebrating the new Quest Seeker's Summer Reading Challenge by delving into secrets of The Joshua Files. 

We also played the game 'So You Think You Know The Joshua Files', for the coveted full set of rare Joshua Files fact cards signed by MG. The winner, 13-year-old Precious, is pictured holding a copy of Invisible City next to MG above.

Quest Seekers can win prizes and tokens by reading 6 (primary school) or 4 (secondary school) books. Learn more at the interactive Quest Seeker's Website.
