The perfect read for anyone who has great affection for London and its "Tube". The author explores those enigmatic destinations at the ends of the lines - places with names which excite the imaginations of those who confine their use of the Underground to city center stations. As I read on with great pleasure, I could almost sense the acrid smell of the still resident soot from the extinct coal burning trains, and hear the cautionary "Mind the gap!" as the carriage doors hiss open. It made me so homesick - and I'm not even English born.
