Balm of Gilead by Aaron Lebold

Ryan has left his entire life behind without telling anyone where he was going. His motivation was selfless. He learned that he had Lou Gehrig’s disease and he wanted his loved ones to remember him as he was. After relocating to Jordan he meets a man who can help him. The task he is faced with in return seems manageable, but only with some help from his old military friends. Once the team is assembled they head off as a group. They have no idea what actually lies ahead.
