Room — Emma Donoghue

To five-year-old Jack, Room is the world. It's where he was born, it's where he and his Ma eat and sleep and play and learn. At night, Ma shuts him safely in the wardrobe, where Jack is meant to be asleep when Old Nick visits.

Room is home to Jack, but to Ma it's the prison where she has been held for seven years. Through her fierce love for her son, she has created a life for him in this eleven-by-eleven-foot space. But Jack's curiosity is building alongside Ma's own desperation -- and she knows that Room cannot contain either much longer.

Room is a tale at once shocking, riveting, exhilarating -- a story of unconquerable love in harrowing circumstances, and of the diamond-hard bond between a mother and her child.
