Welcome to DRAGON OPS, the world's first augmented-reality video-game theme park. Set on a once-deserted island, our three beta players - classic gamer geek Ian; his adventure-seeking sister, Lily; and their too-cool-for-gaming cousin, Derek - have been lucky enough to score an invitation to play before the fully immersive experience opens to the public. But once inside, they find themselves trapped in a game taken over by a rogue AI dragon called Atreus, and suddenly the stakes go beyond the virtual world - and it's life or death.
