In the fevered mind of Samuel Lambent, a storm brews. At its dark heart is a need unlike any other, the kind that ravishes the soul and lays waste to both kindness and sanity. And that storm is mirrored in the skies over Chicago. The Culmination is approaching. For Samuel Lambent is actually Samael – the Fallen One. He’s been dreaming of her, craving her, side-lined by an intense obsession that has all but consumed him. And now that he has actually seen Angel, the long lost fifth and final archess, he will stop short of absolutely nothing to obtain her, going so far as to break fundamental covenants… and make the ultimate sacrifice. Angel watches the skies above with an anxious eye. She knows what the tempest means. The Fallen One has found her. His impossible influence and power stretch across vast miles, and his eyes call to her. Within their tumultuous gray is something her heart understands, no matter how it may not wish to. There is a promise in Samael’s gaze. And it is that promise that keeps her running. For if he claims her. If she gives in… the Culmination will ensue. Life on Earth as she knows it will come to an end. Angel will have surrendered everything. All for the fierce and unforgivable love of the Fallen One. Samael is the nail-biting, gut-clenching, heart-wrenching, long-awaited fifth and final installment in the highly acclaimed The Lost Angels series, by NYT and USA Today bestselling paranormal romance author, Heather Killough-Walden.
