Waite Thomas. Trident Code

Ruthless cyberhackers seize a US nuclear submarine, training its most powerful weapon on a target so unusual, yet so vulnerable, that a successful strike could change the face of the earth for millions of years. With the world held hostage, former NSA operative Lana Elkins must join forces with a mysterious computer mastermind — who might be working with the enemy — to avert this unprecedented Armageddon. Intrigue, power, and blackmail force Lana to fight on all fronts — land, sea, air, and in cyberspace — to prevent the worst catastrophe in human history.
The author of Lethal Code returns with a new geopolitical thriller that combines cyberterror, environmental devastation, and unhinged ambition.
