If We Survive, Paperback/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.
