Orphaned teen Porter Simms agrees to test an experimental technology developed by his late parents. But there's a major catch. He is permanently online, a device of the government, and every time he uses the skills, it takes a toll on his mind.

To make matters worse, an unseen enemy wants him taken offline - for good.

Porter must race to prevent a deadly catastrophe before he loses the most important thing - himself.

A new edge-of-your-seat adventure for fans of Anthony Horowitz and Eoin Colfer.
