In retreat from a devastating loss and crushing injustice, Katie lives alone in a fortresslike stone house on Jacob’s Ladder island. Once a rising star in the art world, she finds refuge in her painting. The neighboring island of Ringrock houses a secret: a government research facility. And now two agents have arrived on Jacob’s Ladder in search of someone—or something—they refuse to identify. Although an air of menace hangs over these men, an infinitely greater threat has arrived, one so strange even the island animals are in a state of high alarm.

An eerie light proclaims the arrival of a mysterious watcher in the woods. And one solitary man begins a desperate battle against something unknown - and unknowable.

Jimmy Tock comes into the world on the very night his grandfather leaves it. As a violent storm rages outside the hospital, Rudy Tock spends long hours walking the corridors between the expectant fathers' waiting room and his dying father's bedside. It's a strange vigil made all the stranger when, at the very height of the storm's fury, Josef Tock suddenly sits up in bed and speaks coherently for the frist and last time since his stroke. What he says before he dies is that there will be five dark days in the life of his grandson.

They're out there...waiting...watching. Unseen by normal eyes, but all too visible to Slim MacKenzie, a young man blessed - or cursed - by Twilight Eyes.

Bill Wile is an easygoing, hardworking guy who leads a quiet, ordinary life. But that is about to change. One evening, after his usual eight-hour bartending shift, he finds a typewritten note under the windshield wiper of his car. If you don’t take this note to the police and get them involved, I will kill a lovely blond schoolteacher. If you do take this note to the police, I will instead kill an elderly woman active in charity work. You have four hours to decide. The choice is yours.
