Drifting in the dark waters of a mysterious river, the only thing Amelia knows for sure is that she's dead. With no recollection of her past life—or her actual death—she's trapped alone in a nightmarish existence. All of this changes when she tries to rescue a boy, Joshua, from drowning in her river. As a ghost, she can do nothing but will him to live. Yet in an unforgettable moment of connection, she helps him survive.
Amelia and Joshua grow ever closer as they begin to uncover the strange circumstances of her death and the secrets of the dark river that has held her captive for so long.
