On the morning of 12 October 2021, Hex woke up. He was expecting to go to work at St. Gart's in London as normal and, that evening, have a great time in the bar of the White Rabbit, celebrating his 23rd birthday. But after his ex-flatmate is wheeled into A&E following a bike accident, and the strange young woman from Human Resources tries to chat him up and an eight-foot-tall guy in a Merc tries to run him down, Hex realises things are not going quite as he expected.
