The first thing you must know about Coraline is that it is CO-RA-LINE and not CA-RO-LINE. Coraline Jones is a girl who has just moved with her parents to a new house. She is an explorer. She is intelligent, curious, resourceful and brave. She is often annoyed with her parents. Her father makes “dishes” she doesn't like to eat and her mother never takes her seriously as she is a little girl. She gets angry when people call her Caroline instead of Coraline.
Coraline is an explorer. In her new house she goes exploring and she finds some really strange neighbours. More importantly, she finds a locked door in the drawing room. When Coraline manages to open it, she finds it is bricked up and is disappointed.
Later at night, she hears a strange noise. She follows it and finds that the door in the drawing room opens into a hole. She finds that it leads to an “other” world with her “other” parents. Unlike her real parents, her other parents are very nice to her. They treat her with love and they feed her with good food. But Coraline is suspicious as they have buttons for eyes. As Coraline explores the other world, she realizes that all is not well and that she must act fast to save herself and her parents.
Coraline is written by Neil Gaiman. It's a horror/fantasy novella. It was awarded the 2003 Hugo Award for Best Novella, the 2003 Nebula Award for Best Novella, and the 2002 Bram Stoker Award for Best Work for Young Readers. I don't know what these awards are meant for, but the way I see it – the more awards, the better.
This book is often compared to Alice in Wonderland and is said to be a more modern version of the same. I hope I've told you enough to help you decide to read it. I hope you enjoy it as much as I did.
