Son of War, Daughter of Chaos — Janette Rallison

Aislynn is accustomed to watching for the enemy. Her parents instructed her from the time she was young to look for people with the signs: greater than normal strength, eyes that can glow green, and the ability to jump long distances. Over the years, Aislynn has come to view her parents' fears as quirks-things that get in the way of having a normal high school life. When Aislynn's mother dies under suspicious conditions, her father doubles his restrictions. But all his precautions can't stop the boy with glowing green eyes from finding Aislynn. She realizes too late she's been drafted into an ancient Egyptian war, whether she's prepared or not.
