When your father is a dead demon prince walking, family dinner is off the table. But stopping him from opening a permanent gateway to Hell? That's a whole different bet. Caleb Lockwood has worked hard to build a life worth living — flipping houses in Las Vegas, falling in love with a psychic who sees right through him, and burying the sins of his past so deep that even he’s almost forgotten them. Then his father Daniel resurfaces with the stolen power of a demon prince and a plan to crack the world open from inside the Luxor pyramid on the black moon. Delia Dunne’s abilities are growing stronger every day, amplified by a pregnancy neither of them saw coming. Her visions all point to the same place: fire, darkness, and forty-eight hours to stop it. But she doesn’t know the full truth about the man she loves — that the quarter-demon who flips houses and charms her with his smile once kidnapped and terrorized innocent people at his father’s command. To take on Daniel, Caleb and Delia need the demon-killing sword last used to destroy Belial, a team of supernatural investigators who remember Caleb as a monster, and an angel’s daughter who still flinches at the sight of him. Assembling a coalition is hard enough. Holding it together when Caleb’s darkest secrets come spilling out may be impossible. Daniel wants his son back, and he’s willing to burn Las Vegas to the foundations to prove that blood always wins. But Caleb isn’t fighting out of rage or revenge. He’s fighting for the woman who chose him and the child they’re building a future for…and destroying his father means destroying the last living embodiment of who he used to be.
