At St. Astor University, vampire student Elden loses control of his rare White Bat ability after an unexpected bite from Lorso, a younger werewolf. The accident triggers a dangerous blood resonance between two natural enemies, leaving Elden's life hanging by a thread.
The campus doctor delivers only one solution: Lorso must regularly donate his blood to keep Elden alive. Bound by a blood pact neither of them wanted, the two are forced into each other's lives.
What begins as reluctant cooperation soon turns into fierce protection, stolen glances, and an undeniable attraction. But as powerful families tighten their grip and a secret research program closes in, the truth behind the so-called "White Bat failure" threatens to destroy everything they've built.
To survive, they'll have to trust each other—and challenge a fate that was written long before they ever met.
