A cracking thriller from No.1 New York Times bestseller Dean Koontz. If you like Jack Reacher or Jason Bourne, you will love rogue FBI agent Jane Hawk.

I could be dead tomorrow. Or something worse than dead.

Rogue FBI agent Jane Hawk knows she's living on borrowed time. But as long as she's breathing, she'll never cease her one-woman war against the terrifying conspiracy that threatens the freedom - and free will - of millions.

Battling the mysterious epidemic of murder-suicides that claimed Jane's husband has made Jane a wanted fugitive, hunted relentlessly by the secret cabal behind the plot. They are determined to see her dead...or make her wish she was.

Propelled by her righteous fury, Jane will confront head-on the lethal forces arrayed against her. But nothing can prepare her for the chilling truth that awaits when she descends the crooked staircase to the dark and dreadful place where her long nightmare was born.
