The Unbroken Oath: A Reverse Harem Vampire Romantasy

An Epic Fantasy Romance Book 2 of the Crimson Collective Series

Enemies are everywhere. Trust is dangerous. And the next oath could break the world.

Kira Shen never expected to survive her first year at Whitecrest Academy, the secret military school where humans train to enforce the new Coexistence Treaty between humans and vampires. But when a second wave of vampire liaisons—collared, monitored, and resented—arrives on campus, Kira is assigned to help one of them: Nyx Vale, a fierce, unpredictable vampire who wants nothing to do with humans… especially her.

Nyx is used to surviving alone. Being forced into a human academy under a treaty she doesn’t believe in is bad enough—but being bound to a suppression collar that punishes every spike of emotion is worse. The last thing she needs is a human partner. But Kira’s stubborn kindness chips through Nyx’s defenses, and their uneasy alliance turns into something neither of them can deny.

When bodies begin disappearing inside Whitecrest’s walls, the blame falls on the new vampire cohort—and the fragile treaty trembles. A hidden extremist faction is working from the shadows, setting traps, sabotaging training drills, and manipulating the academy from within. Their goal is simple: destroy coexistence before it begins.

To stop them, Kira and Nyx must decide whether they trust each other more than the fear that’s been drilled into them since childhood. Their bond could save the treaty… or ignite the war everyone fears.

The Unbroken Oath delivers everything Dark Paranormal Academy Romance readers crave:

• Enemies-to-lovers tension with a forbidden human–vampire bond
• Covert sabotage, political conspiracies, and dangerous secrets
• Academy hierarchy, combat drills, and survival stakes
• Magical suppression collars and high-intensity power reveals
• Found family threads woven through danger and mistrust
• Emotion-first romance with slow-burn heat and explosive chemistry

Perfect for fans of Fourth Wing, Sign of the Slayer, and dark romantasy with academy grit, sharp banter, and forbidden attraction.

Whitecrest Academy is a battleground.
The treaty is a lie held together by fear.
And the most dangerous oath is the one they make to each other.
