"As thrilling as a rollercoaster ride, this fantastical world of spies, spirits, ancient prophecies and hidden cities tests Josh to his limits..." The Booktrust, 2009 by "sci-fi author M.G. Harris, creator of the best-selling Joshua Files." Radio Times Magazine, 5th September 2013.

Josh's dad died in Mexico. He was supposed to be excavating ancient Mayan ruins.
So why was he flying an airplane, hundreds of miles from the site?
And did the UFOs sighted nearby have anything to do with his 'accident'?

Stuck at home with his grief-stricken mother, teenage Josh begins to uncover the truth. His father wasn't on just another archaeological dig. He was searching for a lost Mayan codex thought to contain a prophecy about the end of the world.

Somewhere in the world, Josh's research triggers an alarm.

Now Josh is being tracked by government agents and a hit man from a mysterious sect bent on bringing about a new world order. It all leads to a hidden city buried deep in the Mexican jungle, where an ancient civilization is waiting to be awoken.

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 series for readers who enjoyed tightly-plotted series for children and young adults, like Harry Potter, Percy Jackson and The Maze Runner. A time-travel, code-cracking, action-packed adventure series and coming-of-age story originally published by Scholastic Children's Books UK and translated into 17 foreign languages.

Praise for Invisible City:

  • "A splendid adventure story of UFOs, ancient Mayan documents and a lost city. The hero is eminently likeable, there is a splendid only-you-can-save-the-World denouement and you'll come away with a degree of esoteric knowledge about ancient Central America as well." Louisa Young, 23 March 2008, Mail on Sunday
  • "A fast-paced, first-person thriller. Her book's Mexico setting is richly evoked, and its historical and conspiracy elements are convincingly delineated." James Lovegrove, 2 Feb 2008, Financial Times
  • "A gripping survival story begins...a boy's fantasy of pyramids, caves and tunnels. Josh's quest for a long-lost Mayan text giving the key to salvation is bound up with his personal destiny in an unexpected way. But he is also, like all 13-year-olds, uncertain of what the future will bring. Harris cleverly captures this pivotal period." Carole Mansur, 15 March 2008, The Telegraph
  • "Indiana Jones would have stiff competition in young Joshua Garcia... This series is destined to be a hit...the many mysteries and unanswered questions will have the reader begging for the rest of the series. Highly Recommended." Library Media Connection, September 2010, starred review
  • "An exciting adventure and coming-of-age story with plot twists and cliffhanger chapter endings that will keep you up all night to finish." San Jose Mercury News, 2010
  • "MG Harris proves she has a deft touch and a real skill for writing heart-stopping adventure in her code-cracking debut The Joshua Files: Invisible City. After finding a secret manuscript hidden in the back of a photograph frame, Josh is propelled into a high-speed chase across Mexico. Harris has paced this fast-moving adventure with expertise." Vanessa Curtis, 16 February 2008, The Glasgow Herald

Review

"A fast-paced story of loss, loyalty and personal responsibility which is set firmly in the 21st century." Helen Peacocke, March 2009, The Oxford Times

"An exciting adventure and coming-of-age story with plot twists and cliffhanger chapter endings that will keep you up all night to finish ." San Jose Mercury News

"A gripping survival story begins. Without his friends, miles from a computer, Josh braves snakes and spiders before arriving at a labyrinthine hidden city, a boy's fantasy of pyramids, caves and tunnels. Josh's quest for a long-lost Mayan text giving the key to salvation is bound up with his personal destiny in an unexpected way. But he is also, like all 13-year-olds, uncertain of what the future will bring. Harris cleverly captures this pivotal period." Carole Mansur, Feb 2008, The Telegraph

"Indiana Jones would have stiff competition in young Joshua Garcia, the 13-year-old protagonist of this fast-paced action adventure...This novel is well written, with the action unfolding at a fast and satisfying clip. This series is destined to be a hit. Not only is the non-stop action enthralling, but the many mysteries and unanswered questions will have the reader begging for the rest of the series. Highly Recommended." Library Media Connection, September 2010, starred review

From the Author

This is the book that changed my life! Developing the world of The Joshua Files was a project that rescued me from boredom and depression after a ski accident left me with a broken leg.

I hope you enjoy delving into this world of ancient Mayan codices, glyphic codes and a prophecy of apocalyptic doom, led by teenage Josh Garcia, to whom I will forever be grateful for making my writerly dreams come true.

    3.0 out of 5 stars and the ending collapses like a disturbed soufflé with a disappointing sigh
    Reviewed in the United States on January 27, 2017
    This book is in an odd position. It's marketed as juvenile fiction, and I think younger readers are meant to identify with Joshua, who's only 13. That said, as other reviews have pointed out, he has to deal with the death and mutilation of his father (there's no 11th hour "No, he's only in hiding" here), evidence that his father might have been engaging in adultery, and his mother shutting down in complete depression. Oh, and certain shadowy organizations, officially disavowed by the U.S. government but maybe not really, also want to capture him and torture him for what he knows. He also has some weighty decisions to make about the fate of the human race.

    My rating is somewhere between 2 and 3 stars. This book just does nothing new, and the ending collapses like a disturbed soufflé with a disappointing sigh. Ancient knowledge, government conspiracies, references to the 2012 "Mayan apocalypse"... it sets up some interesting dominoes, knocks a few down, then walks away to do something else. It was not a slog to finish, but I found myself dissatisfied. There's not even a cliffhanger to end, just a "well, these things happened. Let's go back home and try to comfort myself with a facade of normality."

    The young adult genre is something I am probably starting to verge on being too old for, however, I find the genre, especially fantasy and sci-fi great escapism. This novel is a great introduction to what looks like will be a fantastic series. I read the first few pages, settled in and enjoyed a great journey into the unexpected. Looking forward to reading the rest of the series.

    5.0 out of 5 stars Jason Bourne, eat your heart out!
    Reviewed in the United Kingdom on February 4, 2008
    Verified Purchase
    The comparison of Joshua Garcia's quest for the Ix Codex in "Invisible City" with the harebrain antics of Jason Bourne is invidious. Joshua is a character you can really identify with. The storyline twists and soars with every imaginative episode, landing Joshua in new and unpredicted danger.

    We're drawn into the mysterious life of the Maya people, their ancient wisdom and the `long count' calendar that predicts doom for the Earth in December 2012. This knowledge is codified in four books, one of which, the `Ix Codex', is missing. Something unknown links Joshua and his father to its fate. Joshua heads to Mexico to find the cause of his father's death and is drawn inexorably into a chase where he is both hunter and hunted, pursued by undercover agents, people desperate enough to kill to find the Ix secret.

    The moral undercurrent of this fable is undoubtedly the coming of age of 13-year old Joshua. He searches for the Ix Codex but also for the meaning of his life and the dream that haunts him. His aching struggles with unfamiliar feelings are portrayed in a manner that gives the reader insight into the inner turmoil of a boy undergoing the transition towards adulthood. Joshua yearns to prove his father's death was no accident, and then to complete his appointed task. He shows constant loyalty towards his friends and mother - his thoughts expressed through postings to his blog. Ultimately, he is driven by his passions, loyalties and grief to take on every challenge he faces.

    Whilst the book is ostensibly aimed at teenage readers, I found it captivating, with scenes and emotions described in almost sensory detail. The central player is well-characterised, deeply drawn and utterly believable. I was there with every rake and plunge of this roller-coaster adventure.

    I can't wait for the next book in "the Joshua Files" - when's it being published?
