One wrong move, and it's game over.   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 invite 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. With no cheat codes, guidebooks, save points, or do-overs, they'll need all their cunning and video-game hacks to beat the game? and survive in real life.   Action-packed and unputdownable, Dragon Ops will thrill gamers and reluctant readers alike with high-tech adventure and electrifying twists and turns.
