Seduced By The Night

Description for SEDUCED BY THE NIGHT by Robin T Popp:

SEDUCED BY THE MYSTERY...

Dr. Bethany Stavinoski doesn't run from a challenge. As the top biochemist in her field, the delicate-looking blonde routinely puts herself on the line. But her latest research project plunges her into a terrifying world she never knew existed-and into the arms of a dangerous, irresistible man.

SEDUCED BY THE DANGER...

Dirk Adams is a changeling, a human with a vampire's strength and skills. He patrols the darkness to destroy renegade vampires, and he senses something far more powerful behind the relentless pursuers now on Beth's trail. As a nightmare he never imagined unfolds, Beth's only chance to save both their lives is to surrender to Dirk's desperate need...and match his hunger with her own.
