Chatroom (NHB Modern Plays) [EPUB ebook] 

A chilling, blackly comic tale of manipulation, cyberbullying and adolescent insecurity.
In a quiet corner of the internet, a group of bored, restless teenagers spends its time deconstructing children's literature and the messages in modern pop music. But when a new member joins to share his depression and thoughts of suicide, the conversation takes a darker turn.
A powerful depiction of modern-day isolation and the dangerous power of technology, Chatroom formed part of the National Theatre's 2005 Connections season, where it starred Matt Smith and Andrew Garfield.
