The Last Echo

A SERA Archives Adventure Thriller

Not every ghost stays quiet.

War. Mercenaries. Jungle.

When an abandoned Cold War radio station starts transmitting from the South Pacific, SERA agents must confront enemies old and new before history’s deadliest secrets rise again.

Description

A hidden bunker. A forgotten signal. A secret worth killing for.

On a remote island, SERA agents Grant Colson and Luis Fontaine uncover something buried since the Cold War. The secret is something powerful and unexpectedly dangerous. But they’re not alone. Another crew is already on the trail, and they’re not leaving empty-handed.

As a storm batters the South Pacific island and the jungle closes in, the real question isn’t just escape.  It’s who else knows what they’ve found and what comes next.

Inspired by real Soviet eerie number radio stations and one of WWII’s last great mysteries.

Set on Woleai Atoll in the Caroline Islands of Micronesia, a forgotten outpost hundreds of miles south of Guam, this fast-read thriller roots itself in the hidden edges of World War II.

It delivers treachery and betrayal, the tension of buried signals and lost codes, and the isolation of hostile territory where the past refuses to stay buried.

Includes historical notes and briefings from the Strategic Exploration and Recovery Agency Archives.
