"The twistiest murder mystery you are ever likely to read? A story about a family that does the unthinkable? Both? Or something else altogether? You think it will never happen to you. The doorbell. The policeman. The words that turn your world inside out: I'm afraid there's been an incident... For Sally Lambert, those words mean only one thing--danger. Not just for her family, but for Champ, their loyal and beloved dog. A single accusation, a neighbor's grudge, and suddenly the Lamberts are trapped in a nightmare with no escape. Unless they make one. Most people would never run. Most people would never leave behind everything they know to protect an animal who can't defend himself. But for Sally, Champ is more than a dog--he's one of her children. And most people aren't the Lamberts. No one has ever done this before. No one has ever gone this far. But the Lamberts have never been quite like any other family...
