In the wake of her brother's brutal murder, Kate Bishop has a lot of questions. Why was her brother keeping a man chained in his cellar? What was his relationship with the detective now leading the investigation into his death? Could his murder be connected to the death of their reclusive uncle two weeks earlier? One man, the enigmatic author of a book called A Brief History of Evil, contacts Kate saying he has the answers to her questions - answers that will expose her to the nature of true evil. Kate, he says, has a hidden talent, a talent that has marked her for death at the hands of humanity's super-predators... An explosive mix of action and suspense, Nest is a dangerous journey to the back alleys of the darknet, to the darkest corners of our minds, and to the very origins of what it is to be human - a place few have ventured and fewer still have survived.
