Millions of lives depend on one lethal sniper
When his friend disappears without a trace, ex-Marine turned musician Nicholas Sharp embarks on a continent-spanning hunt to find him. The trail leads from the jungles of South America to the warzones of the Middle East, plunging him into conflict with an elite mercenary hit squad. Alongside a radical eco-activist, Sharp uncovers a devastating environmental conspiracy. And when the activist’s son is kidnapped, the ex-Marine must shrug off all restraint to prevent catastrophe.
If he can’t stop the countdown, the world will never be the same
