Immortals walk among us. First in the paranormal series “filled with mesmerizing, breathtaking, scorching sex—[and] unforgettable characters” (Christine Feehan, #1 New York Times–bestselling author).

Falling out of a window is one way to meet your destiny, though it's not something Isabella Ross would have chosen for herself. The shy librarian is irresistibly drawn to the striking man on the dark street outside of her Bronx apartment. And when Bella slips, dropping into his arms, her future—and heart—will be changed forever.

Jacob is a Demon, a race of immortals gifted with nature-oriented powers. As an Enforcer, he is duty-bound to keep his fellow Demons from succumbing to the curse of his species: the madness to mate with humans during a full moon. On that fateful night in the Bronx, he hunts a different prey, a Demon who has been transformed into a hideous monster by a human necromancer.

When Jacob saves Bella, a connection is formed that is at once puzzling and passionate. Although he hasn't lost control in more than four hundred years, Bella stirs a desire in him that overtakes his senses, one that could upend his centuries-old life—and the entire world of the immortals.
