"You will not sleep until you are finished with this book. A superb job creating a set of characters who are fully developed and very much enjoyable. The description of the action scenes transport us into a reality that is almost like sitting in a movie theater with surround sound and 3D (it would make an incredible Hollywood movie). I can hardly wait for the sequel."
--Roberto Mattos, Books and Movie Reviews

This is book #11 in the #1 bestselling series.

When Agent Zero visits his doctor in Switzerland, hoping to salvage his deteriorating health, he is met with a shocking surprise: another agent who has been given a memory implant, just like him. And, just like him, this agent has deadly skills—and a singular mission: to kill Agent Zero.

Agent Zero has met his doppleganger, a darker version of himself.

Who is he? Who does he work for? Who chipped him? What secrets does he hold about Zero's past? And why does he want Zero dead?

This is an un-putdownable espionage thriller that will keep you turning pages late into the night.

"Thriller writing at its best."
--Midwest Book Review (re Any Means Necessary)

"One of the best thrillers I have read this year."
