Signal: A Sam Dryden Novel

From the bestselling author of RUNNER comes the next thriller featuring Sam Dryden, in the series that has captured the imagination of readers worldwide. In the middle of the night, ex-Special Forces operative Sam Dryden gets a urgent call from an old colleague, desperate for his help in a last-minute secret mission. Without a moment's hesitation, Dryden agrees. The two race to a remote shack in the foothills of the Sierra Nevadas, where they break in, rescue four kidnapped girls, then flee into the hills just seconds ahead of the arriving police and FBI team. It's then that Sam Dryden learns the real secret behind this mission. His former teammate has been working security for an old friend whose company discovered something, and developed a device around that discovery, which had the power to change the course of history. But, as Newton's laws predict, for every action, there is an equal and opposite reaction. There are some very bad people determined to get their hands on this device, and will stop at nothing to do so. This hidden group apparently has the money, the connections, the men, and the material to accomplish anything they want. Now the only thing standing in their way is Sam Dryden.
