Ethan Grayson has always chased mysteries. Once a respected archaeologist, now a private investigator with a sharp tongue and a knack for finding trouble, he thought he'd left the ruins and relics of his past behind. But when a dangerous manuscript surfaces—an ancient codex whispered to hold truths worth killing for—Ethan is pulled back into a world where history, obsession, and desire collide.

Drawn to Mexico's forgotten missions and shadowed streets, Ethan finds himself entangled with Isabel Martínez, a brilliant and guarded scholar whose motives are as layered as the codex itself. Their chemistry is undeniable, their attraction reckless, but every step closer to the truth threatens to unravel more than just the secrets of the manuscript.

As cryptic symbols, coded messages, and hidden alliances unfold, Ethan realizes the codex is more than an artifact—it's a key. To power. To knowledge. To something men will murder to possess. And somewhere in the margins of history lies a secret that could rewrite everything he thought he knew about loyalty, betrayal, and love.

But danger doesn't always wear a mask. Sometimes it comes in the shape of an ally. Sometimes in the whisper of a kiss. And as Ethan and Isabel are hunted through jungles, cathedrals, and abandoned missions, he'll have to decide which is more dangerous: the enemies chasing them—or the passion consuming them.

Fast-paced, sharp, and sultry, Secrets of the Codex blends the intrigue of Dan Brown with the rapid-fire dialogue of Aaron Sorkin. It's a story of puzzles and peril, desire and deception, where every revelation comes at a price—and nothing, and no one, is ever as it seems.
