Witch And Vampire: The Ius Coniunctum

The new dark romantasy from rising fantasy voice E. S. Runewick is a razor-sharp blend of power, politics, and slow-burning obsession—where enemies rule side by side… and one misstep could destroy them both. "Cold, intelligent, and utterly addictive. This isn't just romance—it's strategy, tension, and quiet devastation." — Early Reader Review "A masterclass in restraint and power. Every glance feels like a weapon." — ARC Reviewer Don't trust the silence between them. Don't mistake control for indifference. Don't assume the alliance will hold. The city of Vael Moran was never meant to survive this. A witch feared by her own kind. A vampire lord who has ruled for centuries without equal. A binding political marriage that should have ended in blood. Instead, it became something far more dangerous. Three weeks into an impossible co-sovereignty, the system is working—too well. The factions are watching. The wards are deepening beyond known magic. And the fragile balance between witch and vampire is beginning to shift. Maren doesn't believe in distraction. She believes in control, structure, precision. Aldric doesn't believe in uncertainty. He has spent four centuries eliminating it. But something in the east wing is watching back. Something in the magic is changing. And something in the space between them is no longer predictable. The alliance was meant to be temporary. The dissolution papers are already written. So why hasn't either of them signed? As political pressure mounts and unseen forces begin to move, enemies become something else entirely—something neither of them planned for, and neither of them can afford. Because in a city built on power, the greatest threat isn't war. It's choosing. Perfect for fans of: Enemies to lovers Forced proximity / political marriage Morally grey heroine Powerful, ancient vampire MMC Slow burn tension (with payoff) High-stakes political intrigue Intelligent, restrained romance Dual POV Gothic city settings Magic systems with consequences The Ius Coniunctum is a dark romantasy filled with razor-edged dialogue, simmering tension, and a romance built not on fate—but on choice. Expect layered political conflict, subtle power shifts, emotionally charged restraint, and a relationship that unfolds with devastating precision. This is not a story of instant passion. It's a story of control… until control breaks.
