Emma Donoghue’s Room is the latest book club favorite to hit the big screen. And with actress Brie Larson (of recent Trainwreck fame) in the lead role, it’s sure to be an emotional roller coaster. The 2010 novel was short-listed for Britain’s Man Booker Prize and tells the story of a young woman who was kidnapped, locked in a shed and raped repeatedly by her captor for many years.

The book is narrated by 5-year-old Jack, who has only ever seen the 11-by-11 foot shed he was born into. Donoghue also wrote the screenplay for the film, which is directed by Lenny Abrahamson and will hit theaters in October of 2015.
