The Alien Mind (free)

When a group of aliens called the Aruk abduct Rivinaig and several other children, they are thrown into the adventure of a lifetime. The Aunantet, a benevolent race of aliens, rescue the children and adopt them into their culture and raised them as if they belong.
The children's new families teach them how to harness the full capacity of their minds, enabling them to defy the laws of physics and develop special mental abilities.

The past returns to haunt them as the Aruk plot revenge and regain control of their former captives. The fate of the entire galaxy depends on whether the children can maintain their freedom.
