Bill Henderson had an epiphany one day after buying a plot of land high atop a hill in Maine overlooking the sea: why not build a tower "for no reason"? For this lapsed Presbyterian, it all made sense. With his spiritual life in neutral, his marriage struggling, his daughter growing up, a tower was no less appropriate than, say, hiring a shrink or buying a fast car. Ignoring the fact that he knew little about construction, and armed only with a hammer, a handsaw, a tri-square, a tape measure, and a rope, he set about erecting a modest tower upon his not-so-modest hill. Tower is Henderson's down-to-earth study of a sky-high subject that celebrates the dreamer in all of us.
