Joshua Files: #1 Invisible Cities Harris,M,G

Josh's dad was supposed to be on a work trip to Mexico. Instead, he's dead — officially. A climbing accident, they said. But Josh isn't buying it. When a cryptic message leads him to the ruins of an ancient Mayan city, he's pulled into something far stranger than grief: a secret society, a prophecy written in stone, and technology that shouldn't exist. Think *Indiana Jones* meets *Alex Rider* — archaeology, conspiracy, and a teenage boy who's in way over his head. M.G. Harris writes fast-paced YA adventure with real stakes and deeper mythology than most genre fiction bothers with. The Mayan angle is specific, researched, and genuinely intriguing. If you loved *Artemis Fowl* or *Percy Jackson* but wished they leaned harder into real history, this is your entry point.
