Dead Push — Tim O'Rourke

"Most of them just sit as if waiting for someone to join them on their impending journey. Others are rushing for their train as if late for some important meeting. They can't wait to board one of those trains below ground. When I first discovered this place, I don't know how long I sat here watching the dead hustle and bustle about, queue at the ticket office and take drinks from the vending machines. Like any new place you visit, like your first day at a new school or in a new job, you soon figure out how things work. I knew I was dead..." Potter - 'Dead Push' (Kiera Hudson Series Two) Book 8
