Adam Cassidy is twenty-six and a low-level employee at a high-tech corporation who hates his job. When he manipulates the system to do something nice for a friend, he finds himself charged with a crime. Corporate Security gives him a choice: prison—or become a spy in the headquarters of their chief competitor, Trion Systems.

They train him. They feed him inside information. Now, at Trion, he's a star, skyrocketing to the top. He finds he has talents he never knew he possessed. He's rich, drives a Porsche, lives in a fabulous apartment, and works directly for the CEO. He's dating the girl of his dreams.

His life is perfect. And all he has to do to keep it that way is betray everyone he cares about and everything he believes in.

But when he tries to break off from his controllers, he finds he's in way over his head, trapped in a world in which nothing is as it seems and no one can really be trusted.

And then the real nightmare begins. . . .

Readers often ask: "What happened to Adam Cassidy? Will he ever return in another book?" I have no plans to write a sequel to PARANOIA, but my series character, Nick Heller, shares many of the character traits I liked best in Adam. In fact, if you like Adam, you'll definitely like Nick Heller. If only Adam had known Nick, he wouldn't have ended up in all that trouble.
