Neverwhere, by Neil GaimanRead about another entry on the list.
There’s already something magical about London, but the London we know is nothing compared to the dual metropolis of Gaiman’s creation. In Neverwhere we learn there is a London Above and a London Below, the latter being the home of the poor souls who “fell through the cracks in the world.” Murakami lovers will recognize the theme of turning a city over to visit its secret and spellbound underbelly. Gaiman is a fantasy writer through and through, but his genius shines as much for the realism of his characters as for his whimsicality.
