Editorial: Liminality and COVID-19 - what do we already know?

In February 2004, a book was left on my office chair entitled 'Ambiguous loss: learning to live with unresolved grief' (Boss 1999). It was my first day in a position as an allied health Social Worker tasked with managing a missing person counselling service in Sydney, Australia. The book allowed me to consider the ways in which I might therapeutically support people living with the physical absence of a person, whilst struggling with the perplexing nature of the lack of finality. In the last year, this professional reflection has shaped the way I work and research in response to COVID-19.
