I'd like to recommend a book which I read recently, called Marina. The author of the book is Carlos Ruiz Zafon.
The book is a mystery and the setting is Barcelona nowdays. The main characters are two young teens. Oscar, the narrator of the story, who is a boy which is in a boarding school and Marina, a very interesting girl who lives in an old strange house.
The things I liked most about the book were the characters, and the plot. Some of the scenes were really good, but I was a bit scared.
All in all, I have really liked the novel, it has a memorable ending. It's also easy to read and it has a good message about life.
