The loss of a loved one, the end of a relationship, the permanent abandonment of something we consider valuable—these are expressions of the same reality. These phenomenons cause us to sink deeper into sadness and push us toward isolation and despair. In these pages, Jorge Bucay invites us to reflect on one of our most difficult, but at the same time one of the most important,  challenges that all humans must face at one time or another: the grieving process. With his characteristic eloquence, Bucay suggests not only that it is possible to survive the most painful experiences, but also that they are necessary to internally mature and grow.
