Allan Vance lives a meticulously structured life to quiet his chaotic mind, a fragile fortress of order against the whispers of his compulsions. That bastion is shattered when he inherits a mysterious parcel from a dead colleague-a black cube that speaks. The cube reveals itself to be an alien consciousness with a chilling message: An invasion is coming, and humanity is unprepared. Like the mythical Cassandra, Allan is cursed with a terrible gift. He holds the truth about the future, but the world refuses to believe him. When a rebellious alien reveals the invaders' secrets and fatal weakness, Allan, with his astrophysicist friend, Naomi Bell, forges a desperate plan. He must abandon his quiet life for the Alaskan wilderness and race against time to get this impossible truth to the world's leaders. Now, the invasion has begun, and the global battle tests all of humanity, which stands on the brink of collapse. Allan's knowledge is humanity's last, best hope. But can one ordinary man defy all odds and save humankind from certain doom?
