A brilliant hacker.
A chief of a black-ops unit.

An alliance hell-bent on dominating the world.

It's 2007, and the world is edging towards the biggest financial crisis since the Great Depression. A secret international Corporate alliance, known as the cabal, is using the moment to spread its influence.

Helen Chen and Andrew Hunt have little in common. She's a gray hat and he's a senior CIA officer. But when Hunt is tasked to fight the cabal, and Chen becomes the alliance's latest target, they'll have to find a way to help each other or end up like everybody else who tried to stand up to the cabal--dead.

The second book in THE UPGRADE series, VERTIGO is a fast-paced, globe-trotting dystopian tale of intrigue, black ops, and a plot to take over the world.
