The One Safe Place

For the Travises, Americans who have just moved to England, the downward spiral begins with a minor fender bender. Don Travis is shocked when Phil Fancy, the driver of the other car, assaults him. Worse, after Phil is sentenced to prison, Don, his wife, Suzanne, and their adolescent son, Marshall, are targeted for revenge by the rest of the Fancy family.
The Fancys are more than a family - they're a gang, and well practiced at thievery, persecution, assault and battery, and other nasty pursuits. They plague the Travises with harassing phone calls, vandalism at their home, and petty theft at Don's bookshop - but nothing the police can trace to the Fancys.
Pushed to the limit, Don does what would have been unthinkable just a few weeks earlier: he buys a gun. The weapon does him no good when he interrupts the Fancys in an attempt to burn down the bookstore; angered at the mere sight of the gun, the would-be arsonists beat Don to death.
Suzanne and Marshall Travis are stunned, feeling as if the world has shifted beneath their feet. But their ordeal is not over. The younger generation of Fancys has not yet been satisfied. And the focus of their hatred is Suzanne's son, Marshall.
