Providence does not abandon humanity. Out of the darkness, a few girls are born and chosen to fight the forces of evil, chosen to show the light.
A sisterhood is born and forged to wield the power of good. They alone carry the hopes of those in need.

For generations, the Guardians and Demon Hunters have held the vampires, demons, and forces of darkness at bay. Now a new evil emerges, seeking to reclaim an ancient power that would destroy the forces of good and bring forth a new age of terror across the earth.

Sixteen-year-old Isabella O'Brien returns home in time for The Gathering, an event orchestrated by the Guardians that brings together twenty of the best demon hunters on the planet. Izzy, with the help of her newfound friends and fellow demon hunters Grace and Nikki, must find a way to face a new wave of evil that could not only wipe them out, but put an end to the Guardians and bring forth a new age for vampires and creatures of the night.

But can Izzy handle the one weapon that can vanquish this evil, or will it fall into the hands of those she is destined to battle?
