Pronoun (NHB Modern Plays) [EPUB ebook] 

A love story about transition, testosterone, and James Dean.
Josh and Isabella are childhood sweethearts. They were meant to spend their gap year together, they were meant to be together forever. But Isabella has now become a boy.
Pronoun was commissioned as part of the 2014 National Theatre Connections Festival and premiered by youth theatres across the UK. Especially written for young actors, the play can be performed by a cast of seven, with some doubling of roles, or a much larger cast.
