When Alex, Colwyn, and Jacob Lasham exiled the mother of demonkind from Earth 25 years ago, they thought they'd never see her again. Yet evil refuses to stay dead, and Lilith has a score to settle with the trio. She is determined to have Earth as her undisputed realm, and the Lashams will be the first to fall in her renewed war. Alex and Colwyn's daughter Lena has no interest in the family business of destroying demons. She is young and carefree and wants to be normal ... as normal as a clairvoyant quarter-demon can be, anyway. However, Lilith's return threatens her family, and Lena is forced to take up the fight alongside her parents and uncle. This time, Lilith has the upper hand and the destruction of mankind is imminent. Lena discovers that to save the Earth she must do the unthinkable: join forces with the one creature more deadly and profane than even Lilith. But will Lena's agreement with the Father of Lies be worth the lives of all mankind, her sanity, and her soul? Or will she become the gateway for a greater destruction to Earth?
