Blood Hunger (Eclipsing Trilogy, #1)

Eris and Selene Sintas thought their menial Witching lives were simple. That was until the magical barrier protecting their small town vanished in the night, attracting not just the Vampyre's that go bump in the night. Suddenly, the two siblings discover that they have been dragged into a war between the sisters of light and darkness. Now, hunted by creatures stronger than Vampyre's and far more evil, the Sintas Siblings must find refuge before they lose their souls to the Goddess of Darkness.
