Room is a 2010 novel by Irish-Canadian author Emma Donoghue. The story is told from the perspective of a five-year-boy, Jack, who is being held captive in a small room along with his mother.Donoghue conceived the story after hearing about five-year-old Felix in the Fritzl case.

This book really leaves you speechless. Jack sees everything in such an innocent way. I reckon Donoghue does an amazing job impersonating him.
