From #1 New York Times bestselling author of dark psychological suspense and modern classics of mystery and adventure comes a thriller that ventures into science, secrecy and danger.

"I very much need to be dead."

Chilling last words left by a man who had everything to live for but took his own life. People of talent and accomplishment, people seemingly happy and sound of mind, are committing suicide in surprising numbers. A disturbing pattern is beginning to emerge. FBI agent Jane Hawk, recently widowed, is determined to find out why. Which means going rogue and into `the silent corner' - living entirely off the grid even as she hunts her foes. The enemies pursuing her are seemingly endless and unstoppable.

But Jane is as clever as they are cold-blooded, as relentless as they are ruthless. And this one woman will uncover a secret so terrifying that it challenges the limits of science itself.

'The prose, as always in a Koontz novel, is first-rate. Perhaps Koontz's leanest, meanest thriller, this initial entry in a new series introduces a smart, appealing heroine who can outthink as well as outshoot the baddest of bad dudes' Kirkus, starred review

'Readers will clamor for more tales involving Hawk and her quest for justice. Koontz rocks it again' Washington Post
