Finding herself inside a virtual reality steampunk game, a teenager learns she is a member of a pirate crew looking for their captain's lost treasure—a mysterious mechanical contraption. As the gamer searches for pieces of the treasure, she realizes she may be in over her head. If she can piece together the lost machine before the other computerized crew members do, she'll be released from the game. But as she gathers more pieces, she realizes this machine might be bad news in the wrong hands. Is it still worth it to give it to her captain? Who can she trust in a world filled with computer-players?
