Pauline Boss, one of the leading researchers in the field of absence, discusses the concept of ambiguous loss in her book, and offers an expanded concept of grief, which allows one to cope with the emotional and physical damage of loss, without seeking final solutions. Boss warns that the search for closure can be harmful, and that the attempt to find a clear and orderly solution to ambiguous loss is prone to failure. Instead, Boss offers tools and strategies for dealing with ambiguous loss, while retaining its inherent complexity. Boss invites the reader to approach loss sensitively, and to explore the reasons that underlie the complex feelings that accompany ambiguous loss.
