Last Echo: A Post-Apocalyptic Medical Thriller

Six years post-pandemic, Atlanta runs on the currency of blood.

Dr. Avit Arceneaux has spent years rebuilding what humanity lost. The bioengineered pathologist now leads Disease Control Central (DCC), a fragile sanctuary where medical ethics still matter and repopulation efforts flourish in the shadow of the plague.

Then a desperate act of compassion changes everything.

After healing an enemy, Avit is infected with a new variant of the disease that nearly destroyed civilization. As illness spreads and new enemies threaten, his greatest fear becomes reality when his twins are targeted by powerful forces willing to harvest, exploit, and kill for the adaptive future locked inside their DNA.

The world is no longer looking for a cure. It's looking for him.

Avit must cross a shattered landscape of abandoned facilities, hidden colonies, and long-buried secrets while confronting the consequences of a mistake he cannot take back.

As the battle for survival reaches its final reckoning, the fate of his family and the legacy of mankind hang in the balance.

The Last Echo is the gripping conclusion to The Genethic Legacy, a post-apocalyptic medical thriller series where medical catastrophe and biotechnology reshaped humanity, and blood becomes the world's most valuable resource.
