Firstly, it took a while for me to process everything what I just read. And secondly, exams came in between :P. But, without further ado, let's start with the review:) 
 After I finished this book, I felt it was much like 'Alice In Wonderland', but Neil Gaiman made it much, much darker. The story begins with Richard Mayhew, our protagonist,an ordinary guy, who lives an ordinary life in London, but has an extraordinary girlfriend, Jessica, and is engaged to her. Little does he know that his life is about to get 'completely bizarre' when he sees a young girl, Door(yeah, bizarre names, too), injured on the footpath. Breaking off his important dinner with Jessica's boss, he rushes to help Door. And the adventure for him begins. She tells him that she belongs to "London Below" and he is from "London Above." Two dangerous crooks, with heinous crime record, who call themselves, Mr.Croup and Mr. Vandemar(who has a fetish for eating everything alive) are out to kill her. That's how she stepped into "London Above" -through a crack. Richard is not able to make a head or tail of what is going on, until he realizes that he is invisible to everyone. He decides to go to the root of all this mess. For that, he needs to go to "London Below", a completely different world by itself. To know what happens there, you have to read the book:) 
 Neil Gaiman creates an exciting yet terrifying world in "London Below." Death lurks in each and every corner, but people are living with it and are quite content. There are Rat Speakers, saints, angels, monsters, fierce bodyguards, magicians, contract killers, earls, Sewer Folk, pale creatures who suck life and a girl who can open invisible doors. They are the people who have fallen through the cracks in a city called "Neverwhere".Richard is suddenly thrown into this world of danger and mayhem, and has to escape death each time. 
 The adventure which Richard and his friends have, despite their near death experiences, is amazing. The thrill of the ride, including the ending, kept me reeling. He transforms into a brave, strong person, than the meek one he was. Except for few things: (view spoiler)[How did he see Door in the first place? Was he originally from London Below? (hide spoiler)] 
 Other than that, the fantasy adventure, though brutal at times, is a must read for all lovers of this genre.
