Amy Redwing risks everything in her chosen field of dog rescue. She's as reckless as if she plans on living the life–span of a dog herself. When she confronts a violent drunk in order to rescue Nickie, a beautiful golden retriever, Amy has no misgivings. Dogs always do their best, and so will she. Whatever it takes.
Riding shotgun nervously is her friend and lover, Brian, an architect who would marry her if only she were not so committed to these crazy ... heroics! He blames her work for her refusal to marry him. But everything is due to change in the Redwing household.
Someone is trying to destroy Amy. Subtle intrusions escalate into terrifying assaults on everything she holds dear. Amy believes her attacker is Wes Greeley, just released after an eighteen–month stretch, thanks to Amy's testimony, for egregious animal cruelty. But if Greeley is the culprit, it's clear he's not working alone.
At last Amy understands her need of Brian, and a lot more from her troubled past that has been hidden by her passion. Unable to turn to any authority, Amy and Brian are pressed to the edge of a precipice as Koontz's most emotionally devastating thriller races with inexorable speed to a wrenching climax.
