The world's greatest teen spy is back in action in a thrilling new mission: destroy once and for all the terrorist organisation SCORPIA. Following the events of Scorpia Rising, Alex relocates to San Francisco as he slowly recovers from the tragic death of his best friend and caregiver, Jack Starbright, at the hands of terrorists working for SCORPIA. With Jack gone, Alex feels lost and alone, but then, out of the blue, he receives a cryptic email – just three words long, but enough to make Alex believe that Jack may be alive. Armed with this shred of hope, Alex boards a flight bound for Egypt and embarks on a dubious quest to track Jack down. Yet SCORPIA knows Alex's weakness. And the question of whether Jack is alive soon takes a backseat to a chilling new terrorist plot – one that will determine the lives of many. From Egypt to France to Wales, from luxury yachts to abandoned coal mines, Alex traverses a minefield of dangers and cryptic clues as he fights to discover the truth.
