His exploration follows various lives side-by-side, paired together at cliffs, and analyzes the different choices made and divergent paths taken. Two rock musicians confronting a future without the group that had brought them success. Two public figures tainted by scandal having to make decisions about how to rebuild their lives. Two suffragists achieving their epic goal and so left with the puzzle of what to do next. Two figure skaters seeking new purpose when their Olympic careers come to an end. What emerges from Collins’s extensive studies—of writers, actors, scientists, leaders and many others—is a framework for understanding how individual lives can be built, sustained and constantly renewed.
