Cate Rose, the Dark Queen of Hell, has never hesitated to make hard decisions. But this time, the betrayal comes from someone she raised to stand beside her. Devin Black - her fellow heir, her ally, her equal - has gone behind her back to seize power on Earth. His ambitions stretch far beyond the Crimson Brotherhood he leads, and the lengths he has taken to get what he wants leave Cate questioning everything she ever believed about him. Before she can decide his fate, she must understand how it came to this. She must return to the moment it all began. Years earlier, on Earth, a human woman carried a secret the Crimson Brotherhood was desperate to uncover. Her life was shattered the moment Corey Black set his sights on her - using manipulation, charm, and cruelty to drag her into the heart of a dark agenda that would have consequences reaching far beyond her world. Now Cate steps back into the shadows of that past, determined to trace the Brotherhood's rise, the cracks forming within it, and the truth buried beneath decades of calculated betrayal. What she discovers will change not only Devin's future. It will reshape the future of Hell, Heaven, and every throne balanced between them. Old sins are rising. Old powers are stirring. And the cost of balance may demand far more than anyone is ready to pay. Destined for Darkness is the fourth book in the Black Rose dark fantasy romance series - a dual-timeline descent into betrayal, power, and the price of loyalty when the Devil herself must reckon with the truth. Darker in tone and broader in scope, this chapter expands the world of the Rose bloodline into the shadows of Earth, exploring the human casualties left in Hell's wake and the ambitions that fracture even the most powerful alliances.
