About this audiobook
A dead colleague. A package of encrypted letters. And a secret that was supposed to stay buried since the Cold War.
Former NSA signals intelligence analyst Elena Voss traded classified intercepts for quiet lecture halls at Georgetown — until a mysterious parcel drags her back into the shadows. Inside: photocopied letters from WINTERGARDEN, a Cold War dead drop network that was officially shut down decades ago.
Except it wasn't.
As Elena cracks layer after layer of encryption, she uncovers a chilling truth: a network of sleeper agents, planted before the Berlin Wall fell, has reactivated. Their target? A weaponized chimeric virus hidden beneath a prestigious Prague research institute — a doomsday insurance policy engineered in a secret Soviet lab and never recovered.
