Joanna Bourke is an historian whose previous work has looked at fear, pain, sexual violence and dismemberment. Her new book is a history and examination of bestiality and zoophilia, tracing our changing understandings from Leviticus, to modern psychiatry, the animal rights movement, and beyond.

Anna Tsing's book The Mushroom at the End of the World was an examination of human interactions with fungi and their environments, and vice versa, in post-industrial landscapes. Her new online project Feral Atlas charts the complex and shifting relationships between humans, animals, plants, bacteria and other natural phenomena.
