Infiltrating Project Harvest, Delilah must allow herself to become close to Victor. But the bond she's formed with him, and the truth about his work at Project Harvest, cause Delilah to question exactly why the Keepers and Praedari are at war--and to doubt the authenticity of her relationship with Zeke. Things around Project Harvest have taken a turn for the worse for the remaining captives, as an unfriendly face reappears and the Keepers' siege on the facility begins. "The Sacrifice" is book #5 from "Vampire Wars", an EPIC Press series, a division of ABDO.
