Soulless and exiled from Heaven the Dark Knights have spent millennia protecting humanity from Lucifer and his demons. But the longer they live the closer they come to joining Lucifer’s ranks in Hell. Their only hope is to find their soul keepers, and love. After an attack by a demon left her injured and weak Amber Fitzpatrick welcomed the attention and caring of her rescuer Jacob—until he turned into an abusive monster. The night Amber flees the possessive, extraordinarily toxic relationship Jacob reveals his true demonic nature. Zach has more than Lucifer’s minions to contend with. Each day brings him closer to Hell. For fifty years he’s walked the thin line between sanity and giving in to his dark urges. Urges that go against his calling as a healer and a teacher. Every battle drives him closer to the edge, feeds his inner demon and pushes him to find a permanent solution to death. When Zach meets Amber he sees a chance for salvation. But Amber’s experience with Jacob makes her afraid to start any kind of relationship with Zach, especially discovering he’s not that different then the man she walked away from. Can she set her fear aside and save Zach before she loses him to the darkness forever?
