The twenty stories in this collection involve travel back in time where voyagers attempt to change only individual lives and small communities. As a result, do major events remain undisturbed? This theme is explored with surprising mixed outcomes. Imaginative templates include a cave on the dark side of the moon, the ocean floor, a 22 centuries old Peruvian pyramid, and a citywide frozen electricity grid. Time jumps take the reader from 26th century earth to a livable planet Venus 3.8 billion years ago, from present day Poland to its Bronze Age, and from the time of Mao to medieval China. Two brothers reverse the grandfather paradox by keeping theirs alive during a Quebec bridge disaster. A final story examines the possible chaotic consequences of mass producing time machines.
