No one is safe . . . IT’S GORY, IT’S GRIPPING, IT’S GERRITSEN.


Dr Toby Harper’s quiet night is disrupted when a severely ill man stumbles into ER. She suspects a viral brain infection. But shortly after trying to treat him, he disappears without a trace.

When a second person is admitted with the same symptoms, she starts to trace the deadly infection backwards. And begins to suspect foul play.

And that she may be on borrowed time . . .


If you like your crime medicine strong, this will keep you gripped

Mail on Sunday

This is crime writing at its unputdownable, nerve-tingling best

Harlan Coben

Richly drawn hospital scenes . . . Chilling science . . . and breathless ER-style pacing . . . A quick, delightfully scary read


[Gerritsen] has an imagination . . . so dark and frightening that she makes Edgar Allan Poe . . . seem like goody-two-shoes
