Night after night, Mackenzie's dreams return her to a memory from before her sister Sabrina's untimely death: a weekend obscured by a fog of guilt. But when the waking world starts closing in, too, Mackenzie knows this is more than she can handle alone. Traveling to her rural hometown in Alberta, she finds her family still steeped in the same grief she ran away to escape. They welcome her back, but their shaky reunion only seems to intensify her dreams. What really happened that night at the lake, and what did it have to do with Sabrina's death? Only a bad Cree would put their family at risk, but what if whatever has been calling Mackenzie home was already inside?
