Psion Delta (Psion series #3)

Sammy, a fourteen-year-old fugitive, accidentally discovers he has the powers of a Psion.

A six-month journey of incredible trials has brought Sammy back to Capitol Island, but things aren't what they used to be. There are more demons to face and new challenges to overcome. Looming over it all is the war. To make matters worse, big changes are happening in Psion Alpha and Psion Beta—changes Sammy doesn't like.

Katie Carpenter, once the great Queen of Anomaly Thirteens, has fallen from grace, and Sammy is the key to regaining her status.

Commander Byron investigates the depths of Victor Wrobel's treason, and the deeper he searches, the more danger he finds.

The Silent War is at a tipping point; even one boy can be the difference.

But to do so, he must survive.
