When his archaeologist father goes missing after an air crash in Mexico, UFO-obsessed Josh Garcia suspects alien abduction. On the Internet Josh soon finds like-minded friends. But after he discovers his dad was murdered, he's propelled into an urgent race to find a lost book of the ancient Maya.

Could the mysterious 'Ix Codex', missing for centuries, contain the secret to surviving a prophecy of apocalyptic doom?

Josh might be the only person alive who can find it - but there are forces out there who'll do anything to make the prophecy come true.

Will Josh survive long enough to unravel the mystery of what happened to his dad?

Invisible City is the first in a 5-part time-travel adventure series for readers who enjoyed tightly-plotted series for children and young adults, like Harry Potter, Percy Jackson and The Maze Runner.

This debut novel launched an author who later went on to work with Thunderbirds creator Gerry Anderson to develop Gemini Force One. "Puppet-master Gerry Anderson conceived the story for Gemini Force One, but wasn't able to complete it due to the onset of Alzheimer's. The series of novels will now be written by sci-fi author MG Harris, creator of the best-selling Joshua Files." Radio Times Magazine, 5th September 2013.

Praise for Invisible City (The Joshua Files)

Louisa Young, 23 March 2008, Mail on Sunday
