The Wanderer by Fritz Leiber (1965 Hugo Award winner for Best SF novel) has an epic scope made personal. A planet-sized space ship materializes next to the moon and its mere gravitational presence alone causes earthquakes and massive tides that wreck havoc all over the earth. We follow a dozen main characters across the world (well, mostly in the US and England -- there's a token character on the other side of the world) as they struggle to survive the catastrophe, and in a few cases to understand it. Some of the novel rings archaic to my ear (like that token non-Westerner) but it's an adventure both grand and small.
