The Dragon's Revenge

When a multinational games company recruit Tom, a smart, streetwise Dublin teenager, to get a team together and come to San Francisco to immerse themselves in a massive fantasy world, he thinks it is the job of his dreams. His challenge is to level up fast so as to eliminate an AI dragon that has gone rogue and is preventing the release of the game.
As Tom comes closer to that goal, he starts to realise that the game is not what it seems, not least because a powerful cryptocurrency company seem to have funded the creation of the game for their own purposes.
