In the thin glow of moonlight, a mess of auburn curls gleams against the rocks. Hands bound, the girl's fragile body is limp and still. Seconds later, a wall of raging white water crashes down, swallowing her whole... A knock on the door late in the evening can only mean trouble for Detective Josie Quinn, but fear chokes her at the news that one of her own team is missing. No one has seen Denton PD's Press Liaison Amber for days. Sweet-natured and totally dedicated to the job, she'd never let her colleagues down. A message scrawled on the frosted windscreen of Amber's car leads Josie to a nearby dam. But the body they pull from the freezing water is not Amber... Josie won't sleep until she finds a name for the innocent girl left to drown, and the meaning of the numbers scribbled in a tattered pink diary found on Amber's desk. But when the trail leads her to a twisted truth about Amber's family, Josie wonders if anyone really knew her at all? Her team crumbling around her, Josie must stay strong and focused to get the job done. But as prime suspects start going missing, and rumors of an argument the night Amber disappeared surface, could one of her own staff be to blame? Finding Amber alive is Josie's only chance of knowing the truth and stopping a dangerous killer in their tracks. But as a blizzard closes in, how many more precious lives will be snatched before she can?
