The Obsidian Codex (The Atlas Conspiracy Cycle)

Some truths are written in stone. Some are buried in it.

Dr. Elena Vargas was one of the most brilliant epigraphers of her generation — until she staked her name on a forgery and lost everything. Now she teaches bored undergraduates and tries not to remember who she used to be.

Then a colleague sends her a photograph that shouldn't exist: a meter-tall slab of carved obsidian, unearthed in the jungles of Tabasco, its glyphs mapping something no ancient people should have been able to record — the rhythm of earthquakes, centuries before they struck.

To Elena, it's the discovery of a lifetime. To Orpheus Minerals, it's a key to trillions in buried wealth — and they will raze a mountain to own it. As Elena is drawn south into a chase through cartel country and collapsing caverns, she'll have to trust the instinct that once destroyed her, protect a sister who won't stop filming, and outrun an enemy who believes some knowledge is too dangerous to survive.

Because the slab isn't the only thing hidden in the dark. And someone has been erasing discoveries like this for a very long time.

For readers of James Rollins, Clive Cussler, and Dan Brown.

The Obsidian Codex ignites The Atlas Conspiracy — a globe-spanning saga of buried knowledge and the war to keep it hidden. Each book stands alone. Together, they map a secret that can never be buried again.

This book is part of the 6-book The Atlas Conspiracy Cycle series. Each book can be read as a stand-alone, and in any order, but the entire saga takes place over the course of these six books.

The final, seventh book in the cycle will pull together all the threads of the previous six books, and serves as the final chapter of the series.
