Scarecrow and the Army of Thieves (Shane Schofield #3) by Matthew Reilly

He led his men into hell in Ice Station.

He saved the President against all odds in Area 7.

He evaded the world's best bounty hunters in Scarecrow.

He survived unspeakable horrors in Hell Island.

Now he faces his wildest enemy yet...

THE ARMY OF THIEVES

At an abandoned Soviet base in the Arctic, the battle to save the world has begun ...

THE SECRET BASE

It is a top-secret base known only as Dragon Island. A long-forgotten relic of the Cold War, it houses a wespon of terrible destructive force, a weapon that has just been reactivated ...

A RENEGADE ARMY 

When Dragon Island is seized by a brutal terrorist force calling itself the Army of Thieves, the fate of the world hangs in the balance, and there are no crack units close enough to get there in time to stop the Army setting off the weapon.

ONE SMALL TEAM

Except, that is, for a small equipment-testing team up in the Arctic led by a Marine captain named Schofield, call-sign SCARECROW.

It's not a strike force, just a handful of Marines and civilians. It's not equipped to attack a fortified island held by a vicious army. But Scarecrow will lead the team in anyway, because someone has to.

THE ULTIMATE HERO IS BACK, FACING THE ULTIMATE ARMY OF KILLERS.
