At midnight, one of them is dead. By morning, everyone's a suspect. In the stunning yet unsettling Welsh border village of Cwm Coed, Rhys Lloyd has a house full of guests. His vacation homes on Mirror Lake are a success, and he's generously invited the village to drink champagne with their wealthy new neighbors. But by midnight, Rhys will be floating dead in the freezing waters of the lake. Tasked with solving the crime is Ffion Morgan, a detective as fierce and flawed as the landscape she calls home. For Ffion, this case is personal: The suspects are her neighbors, friends, and family, and her search for the killer threatens to reveal the very secrets she's desperate to keep buried. With the community's buried resentments erupting, soon the question isn't who wanted Rhys dead...but who finally killed him. As snow falls over Cwm Coed, suspicion settles in the shadows, and the stillness of Mirror Lake conceals more than a single night's crime. In this village, the truth is never simple
