From a distance, there was an ear-splitting sound that reminded me very much of gunfire. I jumped about a foot off his legs from the unexpected blast. Before I could get a handle on what was going on, I could hear the others above start whooping and hollering at each other. Rowe grabbed me and raced for the tunnel, climbing it smoothly while I did the whole baby monkey imitation by wrapping my arms and legs around his body, holding on for dear life.
