New York Times bestselling author of the Warriors of Poseidon series Alyssa Day returns with a thrilling new series of paranormal romance and a heated battle between good and evil fought to the death on the streets of New York...

Bordertown private investigator Luke Oliver's beat is the dimensional fold in Manhattan between the human and supernatural realms. But now a secret from his past—the League of the Black Swan—has surfaced. Because Luke isn't any ordinary P.I. He's the Dark Wizard of Bordertown, and he never backs down from a fight.

But this time the fight threatens his life and his heart. Rio Jones, the only woman he loved, needs his help against a deadly menace. Luke pushed her away once before, so she'd never fall prey to the curse that threatens to destroy him. He swore he'd never let her go again.

Luke and Rio, with the help of the newly reformed League, must keep evil forces from taking over Bordertown—all the while battling a passion on the razor's edge between danger and desire. And going to take everything they have just to stay alive.
