Never Say Die By Anthony Horowitz

Five weeks after the events of Scorpia Rising, Alex is living in San Francisco, slowly recovering from the death of his best friend and caregiver, Jack Starbright, at the hands of terrorists. Alex feels lost and alone, but then, out of the blue, he receives a mysterious email. It’s just three words long—but it’s enough to make him believe that Jack may be alive after all. Armed with this tiny glimmer of hope, Alex boards a flight bound for Egypt.

But the deadly organization Scorpia isn’t finished yet. As Alex searches for Jack, the pieces of a dangerous puzzle start to emerge… The theft of the world’s most powerful helicopter; evil twin brothers brought up in the Mafia; an operation called “Steel Claw.” Somehow they’re connected and Alex has to find out how if he is to prevent a new terrorist plot.

From a deserted fort in Egypt to a luxury yacht in the South of France and an abandoned mine in the Welsh valleys, Alex has to untangle a web of threats and cryptic clues as he fights to discover the truth.
