Calvary

At sixteen, Julia Percy is told she's destined to save the world from some obscure yet impending calamity. Julia thinks this prophecy is a huge cosmic blunder but submits to ten years of intensive preparation on a paradisiacal planet named Illyria. Now returned to Earth, she faces her first challenge as leader of a group of talented young people who call themselves Calvary. A wraithlike assassin called Banshee has targeted three agents of the Global Peace Federation. These GPF officers have obtained information which, if decoded, could lead to the Banshee's apprehension. But when the first agent of this trio is murdered by the assassin, Calvary's help is enlisted to safeguard the remaining duo. While protecting the officers, Julia quickly learns that Banshee is a deadlier threat than she'd presumed. Calvary becomes embroiled within a figurative crucible, enduring a literal trial by fire. To salvage Calvary and ransom the lives of her dearest friends, Julia must make an impossible choice: forever surrender her freedom or sacrifice her very life.
