Signal

Now with SIGNAL, Patrick Lee and Sam Dryden are back and at the very top of their game.

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 girls before the kidnapper can harm them, 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 of a very special, very secret government project. A project that led to the development of a device which revealed what would have happened to the kidnapped girls if they hadn't intervened as they did. But as Newton's laws predict, for every action, there's an equal and opposite reaction. There are some very bad people determined to get their hands on this device, and every time Sam uses it, now matter how well intentioned, there are hidden and unintended consequences. Consequences that threaten to rip apart his very world and everything that he holds dear.
