Note: Vampire Fight Club was previously published in print as part of the Supernatural anthology. It falls in the Demonica series as book 5.5, and it is also the prequel to Base Instincts.

When a wave of violence that hits too close to home forces shapeshifter and underworld nurse Vladlena Paskelkov to go undercover, her first stop is a haven of vice—with a dangerously sexy vamp in charge . . .

Legendary, jaded, Nathan Sabine is the manager of Thirst, a wildly popular vampire club—and secret underground blood arena. But Nathan, a rare daywalker, possesses other, even more explosive secrets, as does his beautiful new medic, Vladlena. The one thing they can’t conceal is the lust that simmers between them . . .

Now, in an underworld divided by revelry and violence, debauchery and vengeance, Nate and Lena will discover which risks are worth taking—and which desires demand surrender . . .
