The Sacrifice — Lynne Ewing

VANESSA, Serena, Jimena, Catty, and Tianna are five seemingly ordinary girls from Los Angeles. But the truth is that they are all far from ordinary. They each have a secret power that separates them from others--and makes them DAUGHTERS OF THE MOON

Stanton is in love with Serena. But it is a relationship that can never be. Serena is a Daughter of the Moon, a force of good whose mission is to stop him and his kind.

Stanton has been trying to stay away from Serena, but now their secret is out. He will have to choose between the life he has always known and a love that could destroy the person he cares about most.
