Memories are like water. Some float on the surface bright and clear. Some lie deeper - blurred by time and distance. Others rest far from the light in the depths of the darkness. These memories are best forgotten. At the bottom of Asylum Lake the unremembered have grown restless. After the sudden death of his wife, Brady Tanner moves to the small Michigan town where he spent summers as a youth. But he soon learns that small towns can be stained by memories...and secrets too. As Brady is drawn into unearthing the secrets of the town and of the abandoned psychiatric hospital on the shores of Asylum Lake, he discovers a new love in an old friend. But there is an evil presence lurking beneath the waters of the lake. What is the source of this evil - and what does it want with Brady Tanner?
