"And Then There Were None" by Agatha Christie. This book was great in that it was very easy to read, and the suspense was maintained all the way to the end. In other murder mysteries, I might have spent more effort trying to figure out who done it, half way through this book I was just trying to guess who will die next. After all the events have settled, the final solution was very much unexpected for me. Worth reading again.
