A major film starring Brie Larson. Shortlisted for the Man Booker Prize. Shortlisted for the Orange Prize.

Picador Classics edition with an introduction by John Boyne, author of The Boy in the Striped Pyjamas. Today I'm five. I was four last night going to sleep in Wardrobe, but when I wake up in Bed in the dark I'm changed to five, abracadabra.

Jack lives with his Ma in Room. Room has a single locked door and a skylight, and it measures ten feet by ten feet. Jack loves watching TV but he knows that nothing he sees on the screen is truly real - only him, Ma and the things in Room.

Until the day Ma admits there is a world outside. Devastating yet uplifting, Room by Emma Donoghue is a luminous portrait of a boundless maternal love. It has sold more than two million copies, was a number one bestseller and was shortlisted for the Man Booker and Orange prizes.

Few books have reached modern classic status so swiftly. 'Room is a book to read in one sitting. When it's over you look up: the world looks the same but you are somehow different and that feeling lingers for days.' - Audrey Niffenegger, author of The Time Traveler's Wife
