Neverwhere by Neil Gaiman

This book was an enjoyable romp through a wonderfully imaginative world: Under London. Under London is full of the people who slip through the cracks--people who most people living in London Above don't see. This London is almost feudal: divided into baronies and operates via trades. Lord Portico attempts to unite Under London, but is murdered. His daughter Door, in her escape from the assassins who killed the rest of her family, inadvertently brings Richard Mayhew, a Scot living in London Above, into her world. The story is, in part, the story of Richard Mayhew's coming into his own, in a really wonderful way. It is also full of red herrings and diversions. Finally, everything comes together in a convincing and delightful way. I look forward to reading more of Neil Gaiman. The narration on the audiobook was really lovely as well.
