Jed Walker, ex-CIA, is an outsider back in the game. He's been chasing down a sinister group code-named Zodiac that the big guns - MI5, CIA, the Pentagon - have failed to eradicate. But as Walker follows the trail of bodies, uncovering secrets and making connections he's not supposed to make, he finds the answers are closer to home than he ever imagined.
Revenge is the obvious motive, but nothing is ever that simple in love or in war.
Can Walker find who's responsible before the body count grows higher?
Can he stop another terror attack before more innocent bystanders suffer?
When the line between the good and the bad become blurred, when the hunters become the hunted, only one man can save us all.
