Murder the Light — Ash Krafton

Hell hath no fury like a woman scorned-especially the woman scorned by the King of Hell himself. Chiara has been abducted by her own mother: an Enochian defector who has taken up arms against the Light. Luminea will use Chiara to ensure the future of her empire and to burn away her painful past with the man who'd stolen everything from her, so long ago. Unknowingly, that's exactly the guy to who Simon turns for help. He makes the ultimate deal with Chiara's father to get her back...but he'll have the Devil to pay.
