About this book:

Some secrets refuse to stay buried.

When Dr. Amelia Cross inherits a weathered journal from her estranged grandfather—a legendary archaeologist who vanished decades ago in the Amazon—she expects nothing more than a relic of a failed career. But within its pages lies a coded map, cryptic symbols, and a chilling warning: *“The heart of the world is not a myth. It’s a warning.”* As Amelia deciphers the clues, she uncovers evidence of a lost city hidden deep in the jungle, a powerful artifact tied to time itself, and a shadowy organization willing to kill to keep the past buried.

Now, with enemies closing in and time running out before a rare lunar eclipse, Amelia must assemble a team and venture into one of the most dangerous places on Earth—the uncharted depths of the Amazon. But the jungle isn’t the only threat. Betrayal lurks within her own ranks, and the deeper she goes, the more she realizes her grandfather’s disappearance was no accident. In a race against mercenaries, ancient traps, and her own doubts, Amelia must decide: uncover the truth and risk everything… or let the world’s last secret disappear forever.
