In this trio of very short but moving memoirs, the American author Ellis Avery revisits three key moments in her life. Each involves an uncomfortably close encounter with mortality, and a form of grieving, whether that’s for a person she once knew and loved, or a part of her life that is over. The quirky title is taken from the tooth, mounted as a pendant, that Avery finds among her late mother’s jewellery in the first part of this memoir-sequence. It becomes a symbol of the strange remnants that we leave behind us, a mere fragment of the life its unknown owner once lived. The two later memoirs show us Avery dealing with her own mortality, as she confronts a cancer diagnosis. When I first read the three bite-sized books, almost exactly a year ago on 20 February 2019, I found them engaging, pragmatic and compassionate explorations of the way we deal with grief. Little did I realise at the time that Avery had died only five days before I read them. Having read them again, knowing that, her courage and honesty – coupled with a refreshing lack of sentimentality – is all the more striking.
