The story is about thirteen-year-old Conor O’Malley who, in addition to being bullied at school, has nightmares about his mother’s failing health. But the monster he sees outside his bedroom window is real. It’s an ancient tree come to life, who tells Conor stories and asks him to tell the truth. Conor’s relationship with the tree monster helps him come to terms with his mother’s illness. The idea for the book came from award-winning author Siobhan Dowd– whose premature death from cancer prevented her from writing it herself.
The film is being directed by J.A. Bayona, the director of The Impossible and the just-announced World War Z 2 (according to IMDB). Stars attached to the project include Felicity Jones (The Amazing Spider-Man 2) as the boy’s mother and Liam Neeson as the monster.
