Three Guys and a Bar - The Three Guys, #1

The old man, the kid, and the swami build things and they solve problems. They love their projects and stand ready to help, no matter what. So when the occupants of one of their creations ask for their help, they sail to the rescue. However, when they arrive, no one has come down to the dock to greet them. How odd? The three guys soon realize, however, an ancient and deadly fear grips the land. If boundary-pushing allegories beguile you, if you've had to replace your copy of Oh, God! You Devil, treat yourself to "Three Guys and a Bar."
