Circadian Rhythm

Echoes of Decay (A Zombie Apocalypse Series, Book 4)

By: GH Glass

Narrated by: Charles Robert Fox

When the world fell to infection, the last line of defense wasn’t a miracle cure, it was a team of soldiers too stubborn to die. Led by the battle-scarred Dutch, Echo Team has carved a bloody path through a dying Europe. Alongside them, a virologist with too much hope, a spy with too many secrets, and a truth so dangerous it was buried beneath layers of lies. Now, aboard a drifting hospital ship sailing toward a fractured United States, Echo Team carries a final hope: a severed arm taken from Patient Zero in Munich. It’s not much. But it’s all they have. As allies become threats, and new mutations rise from the ashes, Echo Team must fight not only to survive, but to decide who they are in a world where humanity itself is mutating. What started as a mission becomes something far more dangerous: the realization that the infection doesn’t just kill.

It evolves. And so must they. Brutal, cinematic, and filled with sharp wit and heartbreak, this is the story of what happens when the last cure for humanity isn’t a drug, it’s the people willing to stand and bleed for it.
