I enjoyed this after a bit. The first 30 to 40 percent I found slow. But the book picks up momentum and I liked how we get to see more of the London Below via other characters when we're not following the main characters of Richard and Door.
Richard Mayhew finds himself helping a young woman one night and it changes his life forever. Without realizing it, helping the woman named Door will cost Richard his life as he knows it when he finds himself pushed out of his reality. Being lost about what to do, Richard goes looking for Door and finds out about London Below.
I liked Richard though I found him to be a little slow on the uptake sometimes. But I think that Gaiman did a good job of having a readers see things through Richard's eyes.
This book is told in the third person, and we get to follow a number of characters around. We have the Lady Door, the Marquis, and a woman called Hunter who's the best hunter in London Below. When Door goes on a quest to figure out who killed her family and why these four characters end up going on a series of mini-quests.
I kind of like how Gaiman mixes history in this book along with some cultural significance to people who are from Britain.
The writing was good, but as I said above, the flow was off for me for a good portion of the book.
The setting was awesome and I found myself interested in finding out more about those who live in London Below.
The ending felt a bit anti-climatic to me. But all in all, this was a pretty good story.
