As Christmas day nears, Bree and her faithful search-and-rescue dog Samson follow the trail of a troubling mystery into the snowy forests of Rock Harbor.
Bree Matthews is preparing for Christmas guests, but her heart is reeling from the recent and tender loss of her unborn child. Her sister-in-law, Lauri, suddenly turns up on the doorstep of the lighthouse home Bree shares with her husband, Kade, in Rock Harbor. Secretive and withdrawn, Lauri seems curiously intent on discovering what happened to a parachuter who disappeared in the North Woods along Lake Superior's icy shore.
As Bree and Samson, her search-and-rescue dog, plunge into the search, Bree wonders if Lauri may know more than she’s admitted about the parachuter. And then the clues lead them to the trail of a young woman whose family fears the worst about her disappearance.
Will the search on this snowy, silent night lead Bree and Samson to more than clues about the missing girl? And will Bree’s prayer for a baby ever be answered?
