If We Survive oleh Andrew Klavan

They came on a mission of mercy, but now they’re in a fight for their lives.

High schooler Will Peterson and three friends journeyed to Central America to help rebuild a school. In a poor, secluded mountain village, they won the hearts of the local people with their energy and kindness.

But in one sudden moment, everything went horribly wrong. A revolution swept the country. Now, guns and terror are everywhere—and Americans are being targeted as the first to die. 

Will and his friends have got to get out fast. But streets full of killers . . .hills patrolled by armies . . . and a jungle rife with danger stand between them and the border. Their one hope of escape lies with a veteran warrior who has lost his faith and may betray them at any moment. Their one dream is to reach freedom and safety and home.

If they can just survive.
