In the second book of The Watcher Chronicles, Jess finally learns the truth about her father and where he's been ever since the Tear first opened. While Mason tries to keep his distance from Jess in a misguided belief that it will keep her safe, Jess continues to search for the other vessels with Chandler by her side. Their journeys will take them around the world as they seek the missing pieces that will finally make them whole. As the fight against the princes of Hell intensifies, Jess's friendship with Lucifer deepens, but will it be enough to change Lucifer in time to save the world?
