Evelyn Tester is sleepwalking through her suburban life--until a late-night phone call startles her awake. Her husband, a prestigious psychiatrist, has been in an accident. And he isn't alone.

Suddenly Evelyn's world isn't as tidy as she thought. And in the midst of it all is Juliette, not only her husband's secret lover but also his patient. If news of the affair were to get out, it would ruin more than just Evelyn's marriage. Although it's a bitter pill for Evelyn to swallow, protecting her family means staying silent--even if, as she begins to discover, the night of the accident has consequences far more dangerous than the unmasking of an affair.

But the more Evelyn learns about Juliette's picture-perfect life--complete with a handsome, unsuspecting husband--the more she yearns for revenge...and satisfaction. Her growing obsession fuels her rage, burning away her complacency. What will be left of her after it flames out?
