Earth has been invaded by the Illyri--a beautiful, civilized, yet ruthless alien species. But humankind has not given up the fight, and Paul Kerr is one of a new generation of young Resistance leaders waging war on the invaders.

Syl Hellais is the first of the Illyri to be born on Earth. Trapped inside the walls of her father's stronghold, hated by the humans, she longs to escape.
