People have been pulled into the Labyrinth for years, and it's been accepted. But what actually happens in the Labyrinth? People can choose to get back to their homes on Mars, to live in the Labyrinth, or try to get back to Earth. Earth is seen as a safe haven, a place virtuously unknown about since the Martian people lost connection with it over 500 years ago. Grace chooses to survive on her own. Thalia as a leader. Jacob a follower. Matt an adventurer. Elana as a friend, willing to help whoever she can. And Maddie, a thief. Will they make it to Earth? Or will the Labyrinth's mazes and mind puzzles defeat them? No one knows, but only can hope.
