Dan Houser was one of the masterminds behind revolutionary video game series Grand Theft Auto.

Now, after leaving Rockstar Games and launching his own company, he's released a debut novel about a very different type of game.

A Better Paradise is a dystopian vision of the near future in which an AI-led computer game goes rogue.

Set in a polarised world, it finds Mark Tyburn attempting to create a virtual haven for people to find sanctuary and reconnect within themselves against an all-consuming social media hellscape.

But it all goes wrong when it ends up unleashing a mysterious, sentient AI bot named NigelDave into society - "a hyper-intelligence built by humans" - flaws included.
