I finished The Graveyard Book by Neil Gaiman last week, and I loved it. It was a little hard to get into at first, but definitely worth sticking it out. The book is about a little boy who is adopted by the spirits living a graveyard, and his adventures as the only living resident. It's got a cast of really colorful characters, plenty of mystery, and while it has a spooky feel to it, it's not really scary or extremely dark.
(Just an added note: I did read the book in English. xD I only used the French cover of the book in this set because I thought it fit better.)
Also, I know this isn't really my best set. :( I'm sorry.
