Bird Box
Bird Box is a 2014 post-apocalyptic novel and the debut work of Josh Malerman, the lead singer of The High Strung. The book was first published in United Kingdom on 27 March 2014 through Harper Voyager and in the United States on 13 May 2014 through Ecco Press and follows a woman who must find a way to guide herself and her children to safety despite the potential threat from an unseen adversary. The story is partially told via flashbacks and takes place during three different time periods.
Malerman wrote the rough draft of Bird Box prior to the release of the 2008 M. Night Shyamalan film The Happening and the 2009 film The Road, which caused him to worry that the book "might get lost in the shuffle."
