Slave Harvest — Andrew Butcher

Having failed to resist the Scytharene alien attack, Travis and his friends are beamed on board spaceships, along with many other children -- to become slaves. Just when it seems that there is no hope, help arrives from two unexpected sources: Darion, one of the Scytharene, who despises the destructiveness of his race, and a group of scientists, the last remaining adults, who have been hiding underground and have access to some serious weapons. A mission like this will involve great sacrifice -- but will it be enough to end the terror of the Scytharene?
