YouTube star Joe Sugg, younger brother of fellow vlogger Zoella, has signed a deal with Simon & Schuster to release his first graphic novel in September - an 'immersive adventure' about a teenage girl battling to save a virtual world.

Teaming up with author Matt Whyman, Sugg announced the news on his YouTube channel ThatcherJoe, offering fans the chance to choose the name of the main character before saying 'It's going to be great. I know you're going to love it'.
