Conquest

"The first in a stunning new science fiction trilogy, Conquest introduces a world where humanity has been conquered by a powerful alien rulership--unless a group of young rebels can unlock their powers and help rescue humankind from its terrible fate. Earth has been invaded by the Illyri--a beautiful, civilized, yet ruthless alien race. The Resistance grows stronger against the invaders, for it is up to the young people of the Earth to lead the battle and save humanity. Syl Hellais, conceived among the stars, is the oldest alien child on Earth. The daughter of one of the planet's rulers, she has hidden gifts and powers that she does yet fully understand. But all is not as it seems. Secret experiments are being conducted on humans, the Illyri are at war among themselves, and the sinister Nairene Sisterhood has arrived on Earth, hungry for new blood. When Syl helps a pair of young fighters escape execution, she finds herself sentenced to death and pursued by her own kind. Soon, she even risks breaking the greatest taboo of her race by falling in love with a human. Now the hunter has become the hunted, and the predators have become prey. And as Syl is about to learn, the real invasion is yet to begin."
