American Echo

Chronicles of the Cryptologist Series

By: Knox Legend

Narrated by: Donovan Wolfington

For over two centuries, the Custodes Veritatis—a secret society older than the Republic—has shaped American history from the shadows. Presidents, generals, and lawmakers have risen and fallen under their invisible hand. Until now.

When historian Ethan Caldwell uncovers a cryptic message in the journals of Edward Hamilton, he and Mia Hamilton—Edward’s last living relative—are thrust into a conspiracy stretching back to the birth of the nation. Alongside Adler, a gifted cryptographer, they unravel coded journals, hidden chambers, and the lost writings of Dr. Benjamin Church, revealing that America’s true revolution was fought not just on battlefields, but in the shadows.

Their discovery collides with Quentin Vale, a former covert operative, and Orchid, a ghost from his past. Together they unearth a chilling truth: the Custodes Veritatis never died. They are still here, still pulling the strings—and their latest creation sits in the Oval Office.

Pursued through archives and city streets, the trio races to expose a secret that could topple the government and rewrite history itself. From the hidden vaults beneath Carpenter’s Hall to the tunnels under Washington D.C., American Echo is a gripping historical thriller about power, sacrifice, and the cost of truth. Some secrets were never meant to see the light.

National Treasure, but with a darker twist.

If you’re a fan of history, but also love intrigue, you might want to give this book a listen. I thoroughly enjoyed it. Good story, excellent narration, and enough twists to keep you guessing. Is it the best book I’ve ever listened to? No, but it is by far better than the majority. It was entertaining, and sometimes that’s all you need from a book. Hopefully there will be a sequel.

Horrible narration

The attempt at different voices was so annoying it ruined the book. God awful. I should hang previewed the book first.
