From the Back Cover
Derkein glanced around the room in panic and confusion. He saw no one but his father. Then he felt a sharp pain in his arm, heard his shirt tear, and cried out. Something warm dribbled down his arm. When he placed his hand on it and drew it back, he saw blood. His father screamed, and he looked up and saw him flying across the room, crashing into a bookshelf that collapsed under him.
'Dad!' Derkein sprinted towards him but felt a powerful blow across his chest that sent him flying backwards, and he landed hard on the floor, his gun falling out of his hand. Staggering to his feet, he glanced around for whatever had attacked him but saw nothing. His gaze landed on his father, who was groaning ... and then he was gone. There were no bright lights or loud noise. He had just vanished.
