In this fourth decade of the existence of the Two-Track Model of Bereavement, we begin with case material, followed by a history and orientation to the model (Rubin, 1981, 1999; Rubin, Malkinson, & Witztum, 2012). Next, we return to the case and its unfolding over time as viewed through the twin lenses of the model. We conclude with attention to some of the current challenges to the Continuing Bonds field in general, and the Two-Track Model of Bereavement in particular.
