Neverwhere

Richard Mayhew is a young man with a good heart and an utterly ordinary life, which is irrevocably changed when he stops to help a bleeding girl on a London sidewalk. This single act of kindness is a catalyst that erases him from his own reality. Suddenly invisible and forgotten by everyone he knows, his job, his flat, and his very existence in the London he understands are gone. He has fallen through the cracks of the world and into a place he never dreamed existed: London Below.

This is a city of shadows and darkness, of monsters and angels, murderers and saints, that thrives in the subterranean labyrinth beneath the familiar streets. To find his way back, Richard must join the mysterious girl, Door, on her quest to uncover the truth behind her family's slaughter. Navigating a bizarre landscape where assassins are a phone call away and Tube station names take on literal, dangerous meanings, he must learn to survive in this hidden kingdom. The journey reveals a London far more magical and terrifying than the one he left behind, forcing him to question what is real and where he truly belongs.
