I'm reading Sister by Rosamund Lupton. I'm not very far through yet but I'm already engrossed - it's written in the style of a letter from the main character, Beatrice, to her sister as she tries to find out what happened to her. It's full of tension and mystery and the style of writing literally makes you want to turn to the next page and the next... The narrative switches from the present to the past which draws you in - you know snippets of the present but not enough to know the answers to the underlying mystery. I don't know how it's going to end but I'm looking forward to turning more pages and finding out.
Have you read Sister? What did you think of it? (Don't spoil the ending or I'll cry!) What are you reading?
