Life for Grace Maddox was a series of the same ol' same ol' until she flipped over the handlebars of her bike on the way home from work and ended up with a concussion. That's when the dreams began. Quiet dreams. Shimmering dreams. Cold dreams. Dreams of water...always water...a deep pool of water... a waterfall. And something in the water, at the bottom of the pool. A dead body with her face. That's when Grace would wake up screaming. Of course, they were just dreams, probably brought on by the concussion...right? Or could they be a warning?
