Recently transferred to the Center Harbor Police Department in the dead of winter, Detective Lucas York is on the downhill slide of a once-promising career when he's called to Squam Lake where a body lies trapped beneath a thick sheet of ice. The victim, beautiful and respected, appeared to have the perfect life-a charming husband, an adorable baby boy, an idyllic estate a mere breath away from the lake. She also appears to have the face of a woman with whom Lucas shared a dark, lustful night nearly a decade ago, one that has haunted him into obsession. It's been years since Holly Danes has seen her identical twin, a fact she both regrets and rationalizes. Rose had her secrets and it tore them apart, but nothing can prepare Holly for the dangerous world she must infiltrate in order to catch a killer who left no clues. Peeling back the layers of her twin's troubled past, she slips into Rose's life in search of answers. And the deadly game of cat and mouse that results traps her with the one man whose need to uncover the truth is as intense as her own. But can she trust Lucas when this case begins to stir the most volatile of human emotions in his heart? As Lucas and Holly sift through the circumstances of Rose's increasingly disturbing lifestyle, a stunning discovery changes everything they thought they knew about the enigmatic woman. And when the killer strikes again and again, they are pulled down a deceiving trail of smoke and mirrors, unaware that someone very close to them is the murderous psychopath.
