Have you read 'Room' by Emma Donoghue? I didn't read it last year - I bought it yesterday and I've been whizzing through it. Amazing stuff.
It's about a little boy called Jack (age 5) and his mother, and they're locked inside a room and not allowed to leave. Based mildly on the Fritzl saga (but don't let that put you off) and told from Jack's point of view. It's just wonderful.
