Another teen book is being made into a movie! How I Live Now by Meg Rosoff is the story of Daisy, a 15 year old from New York city who goes to live with her aunt and cousins in rural England to escape her stepmother. Soon after she gets there, war breaks out and tears apart her new family.
The movie is scheduled to come out in 2013, but no specific date yet. Saoirse Ronan is going to star. You may know her from The Lovely Bones. If not, you will soon know her from the movie version of The Host (Stephenie Meyer's non-Twilight book).
