The Plantation by Stella Samiotou Fitzsimons

When the light of the human species vanished, there was a girl… and a spark.

In the not-so-distant future, aliens have wiped out society and use human children as slaves. In this fast-paced adventure, 17-year-old Freya must face her destiny when a friend whisks her away to join a rebellion. The small band of rebels known as Saviors just may be the only hope for the human race.
